300mA Variable Output
Industrial LDO Regulator
BDxxGA3MEFJ-LB
General Description
This is the product guarantees long time support in Industrial market.
BDxxGA3MEFJ-LB is a LDO regulator with output current 0.3A. 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.
