FAST-TRANSIENT-RESPONSE 500mA LOW-DROPOUT VOLTAGE REGULATORS

• Open Drain Power-On Reset with 200ms Delay

The TPS775xx and TPS776xx devices are designed

(TPS775xx)

to have a fast transient response and be stable with a

10 µ F low ESR capacitor. This combination provides

Power good (PG) of the TPS776xx is an active high

output, which can be used to implement a power-on

reset or a low-battery indicator.

The TPS775xx and TPS776xx are offered in 1.5V,

1.6V (TPS77516 only), 1.8V, 2.5V, 2.8V (TPS77628

only), and 3.3V fixed-voltage versions and in an

adjustable version (programmable over the range of

1.5V to 5.5V for the TPS77501 and 1.2V to 5.5V for

the TPS77601). Output voltage tolerance is specified

as a maximum of 2% over line, load, and temperature

ranges. The TPS775xx and TPS776xx families are

available in 8-pin SOIC and 20-pin TSSOP packages.
