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.
