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 s. With zero shutdown current and low ground current of 55 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 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
