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 R_ON P−channel pass element with internal
control circuitry which prevents reverse current flow should the
voltage at V_OUT exceed V_IN as in the case of the car’s battery voltage
accidentally being applied to V_OUT.
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 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_IN
and will not conduct current backwards into its supply.
CAT6201 is available in 8−pad 2 mm x 3 mm TDFN package.
