Description

General part information

TPS7A80 Series

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.
