Linear Voltage Regulator, 300 mA, LDO

The CAT6220 is a 300 mA CMOS low dropout regulator whose output voltage is user adjustable that provides fast response time during load current and line voltage changes.

With 1 µA of shutdown current, an internal no-load operating current of only 10 µA, and full-load operating current of 40 µA, the CAT6220 is ideal for battery-operated devices with supply voltages from 2.3 V to 6.5 V.

The CAT6220 offers 1% initial accuracy and low dropout voltage, 270 mV typical at 300 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 device is available in the low profile (1 mm max height) TSOT-23-5 and 2 mm x 2 mm TDFN-6 packages.
