3 Description
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.
