Description
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.
