TPS7A80 1 A Low-Dropout (LDO) Linear Regulator

Texas Instruments' TPS7A8012DRBT is a low-noise, high-bandwidth PSRR, 1 A LDO linear regulator

Image of Texas Instruments' TPS7A8012DRBT 1A Low-Dropout (LDO) Linear RegulatorTexas Instruments' TPS7A80 family of LDOs offer very high power-supply ripple rejection (PSRR) at the output. This LDO family uses an advanced BiCMOS process and a PMOSFET pass device to achieve very low noise, excellent transient response, and excellent PSRR performance.

The TPS7A80 family is stable with a 4.7 µF ceramic output capacitor and uses a precision voltage reference and feedback loop to achieve a worst-case accuracy of 3% overall load, line, process, and temperature variations.

This family is fully specified over the temperature range of TJ = -40°C to +125°C, and is offered in a 3 mm x 3 mm, VSON-8 package with a thermal pad.
