DESCRIPTION
The CAT6219 is a 500mA 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 150μs. With zero shutdown current and low ground current of 55μA typical, the CAT6219 is ideal for battery- operated devices with supply voltages from 2.3V to 5.5V. An internal under voltage lockout circuit disables the output at supply voltages under 2.15V typical. The CAT6219 offers 1% in itial accuracy and low dropout voltage, 300mV typical at 500mA. Stable operation is provided with a small value ceramic capacitor, reducing required board space and compo- nent cost. Other features include current limit and thermal protection. The LDO is available in fixed and adjustable output in the low profile (1mm max height) 5-lead TSOT23 and in the 6-pad 2mm x 2mm TDFN packages. For Ordering Information details, see page 9.

Typical application circuit with external components is shown on page 1. (1) Exceeding maximum rating may damage the device. allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. (3) The device is not guaranteed to work outside its operating rating.
