CAT6219

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 150s.

With zero shutdown current and low ground current of 55A 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% initial accuracy and low dropout voltage, 300mV typical at 500mA. Stable operation is provided with a small value ceramic capacitor, reducing required board space and component cost.

Other CAT6219 features include current limit and thermal protection.

CAT6219 is available in the low profile (1mm max height) 5-lead thin SOT23 and in the 6-lead 2mm x 2mm TDFN packages.
