CAT6202
500 mA / 13 V Adjustable
CMOS LDO Regulator
Description
The CAT6202 is a 13 V rated 500 mA CMOS low dropout regulator
that provides fast response time to load current and line voltage
changes in an automotive environment.
CAT6202 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.
CAT6202 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.
CAT6202 is available in 8−pad 2 mm x 3 mm TDFN package.

3. Dropout voltage is defined as the input−to−output differential at which the output voltage drops 2% below its nominal value. During test, the
input voltage stays always above the minimum 3.3 V. The given values are for VOUT = 7.5 V.
