Cxld6434 series is a high-speed, low-pressure differential developed with CMOS technology,High precision output voltage, low consumption current positive voltage voltage regulator

Cxld6434 series is a high-speed, low-pressure differential developed with CMOS technology,
High precision output voltage, low consumption current positive voltage voltage regulator. Because of the built-in low-pass resistance transistor, the differential pressure is low and the output current can be larger. In order to make the load current not exceed the current capacity of output transistor, overload current protection circuit and short circuit protection circuit are built in
