The CAT6201 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 features a low R
P-channel pass element with internal control circuitry which prevents reverse current flow should the voltage at V
exceed V
as in the case of the car's battery voltage accidentally being applied to V
.
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 (
) provides an alert should an over-current event or thermal shutdown occur.
CAT6201 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 V
and will not conduct current backwards into its supply.br>
CAT6201 is available in 8-pad 2 mm x 3 mm TDFN package.
