Low Dropout Regulators (LDOs)

Diodes' low dropout regulators offer a wide range of features to fit many applications

Image of Diodes Low Dropout Regulators Low dropout regulators (LDOs) from Diodes Incorporated are a simple and cost-effective way to get a regulated output voltage from a higher input voltage. LDOs provide great simplicity for the system design, as they are widely used in broad applications due to no switching noise and small size. Diodes Incorporated has a broad portfolio of LDOs which offer many different features such as ultra-low IQ, high PSRR, wide input voltage, small size, and high current.

Small-size LDOs: reduce form factor

Electronic designs are getting denser and denser and PCB space is consequently getting smaller and smaller. Diodes' small-size LDOs address this challenging task and deliver the same high-quality performance while consuming as little space as possible.

High PSRR LDOs: clean up the power supply

High PSRR LDOs effortlessly power any system in a rough power supply environment. They provide high rejection on the power supply noise to provide clean DC power to ensure system reliability.

Low IQ LDOs: save power

Low IQ LDOs can help to extend the battery life of the increasing number of essential battery-powered devices. Preserving energy is the task of electronic devices, and by minimizing the quiescent current of an LDO, these products help to achieve low standby power across a variety of applications.

Wide input voltage LDOs: increase reliability and robustness

Diodes' wide input voltage LDOs up to 40 V provide simple, cost-effective solutions to supply MCUs, embedded systems, sensors, and other active components when facing a high-voltage environment. The high accuracy and current limit functions make any design more reliable and robust.

High-current LDOs: heavy load, avoid switching noise

Switching noise can threaten performance in many applications. Diodes' high-current LDOs up to 3 A provide clean, accurate, and efficient power for heavy, sensitive loads. Additional high-PSRR featured LDOs eliminate ripple, offer high output accuracy (1% max), and deliver low dropout of 330 mV and below.

Automotive LDOs: compliant to AEC-Q100 with a Grade 1 (-40°C to +125°C) temperature rating

Diodes' automotive LDOs feature a high power supply rejection ratio (PSRR) of 75 dB at 1 kHz to deliver stable output voltages suitable for automotive applications, such as point of load power supplies in ADAS, RF communications, cameras, and infotainment systems. The products are available with or without an output discharge function.
