Texas Instruments  TPS7A8001DRBR

The TPS7A80 family of low-dropout linear regulators (LDOs) offer very high power-supplyripple rejection (PSRR) at the output. This LDO family uses an advanced BiCMOS process and aPMOSFET pass device to achieve very low noise, excellent transient response, and excellent PSRRperformance.

The TPS7A80 family is stable with a 4.7-µF ceramic output capacitor, and uses a precisionvoltage reference and feedback loop to achieve a worst-case accuracy of 3% over all 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 × 3-mm, VSON-8 package with a thermal pad.
