Recommended alternative parts

  • TPS7A91  -  TPS7A91 is the next-generation version of this device with lower noise and lower dropout.
  • TPS7A88  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.   TPS7A88 is a dual-channel, low noise, 1-A LDO.


The TPS7A8101 low-dropout linear regulator (LDO) offers very good performance in noise and power-supply rejection ratio (PSRR) at the output. This LDO uses an advanced BiCMOS process and a PMOSFET pass device to achieve very low noise, excellent transient response, and excellent PSRR performance.

The TPS7A8101 device 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% over all load, line, process, and temperature variations.

This device is fully specified over the temperature range of TJ = –40°C to 125&#deg;C and is offered in a 3-mm × 3-mm, SON-8 package with a thermal pad.
