BD00IA5MEFJ-M
Automotive 0.5A Variable Output LDO Regulator

BDxxIA5MEFJ-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 0.8V to 4.5V).It has package type: HTSOP-J8. Overcurrent 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.
