CAT6217 - Catalyst Semiconductor

CAT6217 150mA CMOS LDO Regulator

The CAT6217 is a 150mA 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 CAT6.
