Description

The CAT6201/CAV6201B is a 13 V rated 300 mA CMOS low

dropout regulator that provides fast response time to load current and

line voltage changes in an automotive environment.

CAT6201/CAV6201B features a low RON P−channel pass element

with internal control circuitry which prevents reverse current flow

should the voltage at VOUT exceed VIN as in the case of the car’s

battery voltage accidentally being applied to VOUT.

Thermal protection and current limiting circuitry combine to protect

the pass device against faults and abuse. Current limiting is user

controlled through a single resistor to ground. A fault output (FLT)

provides an alert should an over−current event or thermal shutdown

occur.

CAT6201/CAV6201B comes on−line gracefully even though it may

be driving heavy capacitive loads thanks to built−in soft−start

circuitry. Its output is protected against accidental connection to

voltages greater than VIN and will not conduct current backwards into

its supply.

CAT6201/CAV6201B is available in 8−pad 2 mm x 3 mm TDFN package.
