0.5A Variable Output Industrial LDO Regulator - BD15IA5MEFJ-LB(H2)

This is the product guarantees long life cycle in Industrial market.
BD15IA5MEFJ-LB is a LDO regulator with output current 0.5A. The output accuracy is ±1% of output voltage. 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 shutdowncircuit (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.
