Product Overview
Product Description
The CAT6219 is a 500 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 µs.

With zero shutdown current and low ground current of 55 µA typical, the CAT6219 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 2.15 V typical.

The CAT6219 offers 1% initial accuracy and low dropout voltage, 300 mV typical at 500 mA. Stable operation is provided with a small value ceramic capacitor, reducing required board space and component cost.

Other features include current limit and thermal protection.

The LDO is available in fixed and adjustable output in the low profile (1 mm max height) 5-lead TSOT23, 6-pad 1.5 mm x 1.5 mm WDFN and in the 6-pad 2 mm x 2 mm TDFN packages.
