CAT6219
500 mA CMOS LDO
Regulator
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 m s.
With zero shutdown current and low ground current of 55 m A
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

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.
