1A Variable / Fixed Output
LDO Regulator
BDxxGC0WEFJ
●General
Description
BDxxGC0WEFJ is a LDO regulator with output current 1.0A. The output accuracy is ±1% of output voltage. With external
resistance, it is available to set the output voltage at random (from 1.5V to 13.0V) and also provides output voltage fixed
type without external resistance. It is used for the wide applications of digital appliances. It has package type: HTSOP-J8.
Over current protection (for protecting the IC destruction by output short circuit), circuit current ON/OFF switch (for setting
the circuit 0μA at shutdown mode), and thermal shutdown circuit (for protecting IC from heat destruction by over load
condition) are all built in. It is usable for ceramic capacitor and enables to improve smaller set and long-life.
●Features
High accuracy reference voltage circuit
Built-in Over Current Protection circuit (OCP)
Built-in Thermal Shut Down circuit (TSD)
With shut down switch
