CAT6217
150 mA CMOS LDO Regulator
Description
The CAT6217 is a 150 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 ms.
With zero shutdown current and low ground current of 55 mA typical, the CAT6217 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 2.1 V typical.
The CAT6217 offers 1% initial accuracy and low dropout voltage, 90 mV typical at 150 mA. Stable operation is provided with a 1 mF ceramic capacitor, reducing required board space and component cost.
