Low-Noise, High-Bandwidth PSRR, 1A Low-Dropout (LDO) Linear Regulator

Low-Noise, High-Bandwidth PSRR, 1A Low-Dropout (LDO) Linear Regulator - TPS7A80

Recommended alternative parts

  • TPS7A88  -  TPS7A88 is a dual-channel, low-noise, 1-A LDO.
  • TPS7A91  -  TPS7A91 is the next-generation version of this device with lower noise and lower dropout.
  • TLV757P  -  TLV757P is a single-channel, low-Iq, 1-A LDO.


The TPS7A80 family of low-dropout linear regulators (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% 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.
