CAT6218
LDO Regulator - CMOS
300 mA
Description
The CAT6218 is a 300 mA CMOS low dropout regulator that provides fast response time during load current and line voltage changes.
The quick−start feature allows the use of an external bypass capacitor to reduce the overall output noise without affecting the turn−on time of just 150 ms.
With zero shutdown current and low ground current of 55 mA typical, the CAT6218 is ideal for battery−operated devices with supply voltages from 2.3 V to 5.5 V. An internal under voltage lockout circuit disables the output at supply voltages under 2.1 V typical.
The CAT6218 offers 1% initial accuracy and low dropout voltage, 180 mV typical at 300 mA.
