CAT6201
300 mA / 13 V Adjustable
CMOS LDO Regulator
Description
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 RON Pchannel 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 overcurrent event or thermal shutdown
occur.
CAT6201 comes online gracefully even though it may be driving
heavy capacitive loads thanks to builtin softstart circuitry. Its output
is protected against accidental connection to voltages greater than VIN
and will not conduct current backwards into its supply.
CAT6201 is available in 8pad 2 mm x 3 mm TDFN package.
