CAT6201B数据手册ONSEMI中文资料规格书

描述 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 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 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.br>CAT6201 is available in 8-pad 2 mm x 3 mm TDFN package.
