Automotive 0.5A Variable Output
LDO Regulator
BDxxGA5MEFJ-M
●General
Description
BDxxGA5MEFJ-M is a LDO regulator with output current 0.5A. 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).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
AEC-Q100 Qualified
