7 Detailed Description
7.1 Overview
The TLV1117LV family of devices are a series of low quiescent current, high PSRR LDOs capable of handling up
to 1 A of load current. These devices feature an integrated current limit, thermal shutdown, bandgap reference,
and UVLO circuit blocks.
7.2 Functional Block Diagram
7.3 Feature Description
7.3.1 Internal Current Limit
The TLV1117LV internal current limit helps to protect the regulator during fault conditions. During current limit,
the output sources a fixed amount of current that is largely independent of the output voltage. In such a case, the
output voltage is not regulated, and can be calculated by the formula: VOUT = ILIMIT × RLOAD. The PMOS pass
transistor dissipates (VIN – VOUT) × ILIMIT until thermal shutdown is triggered and the device turns off. As the
device cools down, it is turned on by the internal thermal shutdown circuit. If the fault condition continues, the
device cycles between current limit and thermal shutdown. See the Thermal Information section for more details
The PMOS pass element in the TLV1117LV device has a built-in body diode that conducts current when the
voltage at OUT exceeds the voltage at IN. This current is not limited; if extended reverse voltage operation is
anticipated, external limiting to 5% of the rated output current is recommended.
7.3.2 Dropout Voltage
The TLV1117LV uses a PMOS pass transistor to achieve low dropout. When (VIN – VOUT) is less than the
dropout voltage (VDO), the PMOS pass device is in the linear region of operation and the input-to-output
resistance is the RDS(ON) of the PMOS pass element. VDO scales approximately with output current because the
PMOS device behaves as a resistor in dropout.
As with any linear regulator, PSRR and transient response are degraded as (VIN – VOUT) approaches dropout.

Feature Description (continued)
7.3.3 Undervoltage Lockout
The TLV1117LV uses an undervoltage lockout (UVLO) circuit keep the output shut off until internal circuitry
operating properly.
7.4 Device Functional Modes
7.4.1 Normal Operation
The device regulates to the nominal output voltage under the following conditions:
The input voltage is greater than the nominal output voltage added to the dropout voltage.
The output current is less than the current limit.
The device die temperature is lower than the thermal shutdown temperature.
7.4.2 Dropout Operation
If the input voltage is lower than the nominal output voltage plus the specified dropout voltage, but all other
conditions are met for normal operation, the device operates in dropout mode. In this condition, the output
voltage is the same the input voltage minus the dropout voltage. The transient performance of the device is
significantly degraded because the pass device is in a triode state and no longer controls the current through the
LDO. Line or load transients in dropout may result in large output voltage deviations.
Table 1 shows the conditions that lead to the different modes of operation.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TLV1117LV is a low quiescent current linear regulator designed for high current applications. Unlike typical
high current linear regulators, the TLV1117LV series consume significantly less quiescent current. These devices
deliver excellent line and load transient performance. The device is low noise, and exhibits a very good PSRR.
As a result, it is ideal for high current applications that require very sensitive power-supply rails.
This family of regulators offers both current limit and thermal protection. The operating junction temperature
range of the device is –40°C to +125°C.
8.2 Typical Application
Figure 27 shows a typical application circuit.
Figure 27. Typical Application Circuit
8.2.1 Design Requirements
For this design example, use the parameters listed in Table 2 as the input parameters.
Table 2. Design Parameters
PARAMETER DESIGN REQUIREMENT
Input Voltage 2.5 V to 3.3 V
Output Voltage 1.8 V
Output Current 500 mA
8.2.2 Detailed Design Procedure
8.2.2.1 Input and Output Capacitor Requirements
For stability, 1.0-μF ceramic capacitors are required at the output. Higher-valued capacitors improve transient
performance. TI recommends the X5R- and X7R-type ceramic capacitors because these capacitors have
minimal variation in value and equivalent series resistance (ESR) over temperature. Unlike traditional linear
regulators that need a minimum ESR for stability, the TLV1117LV series are ensured to be stable with no ESR.
Therefore, cost-effective ceramic capacitors can be used with these devices. Effective output capacitance that
takes bias, temperature, and aging effects into consideration must be greater than 0.5 μF to ensure stability of
the device.

Although an input capacitor is not required for stability, it is good analog design practice to connect a 0.1-μF to
1.0-μF, low-ESR capacitor across the IN pin and GND pin of the regulator. This capacitor counteracts reactive
input sources and improves transient response, noise rejection, and ripple rejection. A higher-value capacitor
may be necessary if large, fast rise-time load transients are anticipated, or if the device is not located physically
close to the power source. If source impedance is greater than 2 Ω, a 0.1-μF, the input capacitor may also be
necessary to ensure stability.
8.2.2.2 Transient Response
As with any regulator, increasing the size of the output capacitor reduces overshoot and undershoot magnitude.
8.2.3 Application Curves
Figure 28. Load Transient Response 200 mA to 500 mA, Figure 29. Line Transient Response VOUT = 1.8 V, IOUT =
COUT = 1 μF 500 mA
8.3 Do's and Don'ts
Place input and output capacitors as close to the device as possible.
Use a ceramic output capacitor.
Do not use an electrolytic output capacitor.
Do not exceed the device absolute maximum ratings.
9 Power Supply Recommendations
Connect a low output impedance power supply directly to the INPUT pin of the TLV1117LV. Inductive
impedances between the input supply and the INPUT pin can create significant voltage excursions at the INPUT
pin during startup or load transient events.

10 Layout
10.1 Layout Guidelines
Input and output capacitors should be placed as close to the device pins as possible. To improve characteristic
AC performance such as PSRR, output noise, and transient response, TI recommends designing the board with
separate ground planes for VIN and VOUT, with the ground plane connected only at the GND pin of the device. In
addition, the ground connection for the output capacitor should be connected directly to the GND pin of the
device. Higher value ESR capacitors may degrade PSRR performance.
10.2 Layout Example
Figure 30. Layout Example
10.3 Thermal Protection
Thermal protection disables the output when the junction temperature rises to approximately 165°C, allowing the
device to cool. When the junction temperature cools to approximately 145°C, the output circuitry is again
enabled. Depending on power dissipation, thermal resistance, and ambient temperature, the thermal protection
circuit may cycle on and off. This cycling limits the dissipation of the regulator, protecting it from damage as a
result of overheating.
Any tendency to activate the thermal protection circuit indicates excessive power dissipation or an inadequate
heatsink. For reliable operation, junction temperature should be limited to 125°C maximum. To estimate the
margin of safety in a complete design (including heatsink), increase the ambient temperature until the thermal
protection is triggered; use worst-case loads and signal conditions.
The internal protection circuitry of the TLV1117LV has been designed to protect against overload conditions. It
was not intended to replace proper heatsinking. Continuously running the TLV1117LV into thermal shutdown
degrades device reliability.
10.4 Power Dissipation
The ability to remove heat from the die is different for each package type, presenting different considerations in
the printed circuit board (PCB) layout. The PCB area around the device that is free of other components moves
the heat from the device to the ambient air. Performance data for JEDEC low and high-K boards are given in the
Thermal Information table. Using heavier copper increases the effectiveness in removing heat from the device.
The addition of plated through-holes to heat-dissipating layers also improves heatsink effectiveness.
Power dissipation depends on input voltage and load conditions. Power dissipation (PD) is equal to the product of
the output current and the voltage drop across the output pass element, as shown in Equation 1:
