BDJ2FA1FP3
100mA Fixed Output LDO Regulator

BDJ2FA1FP3 is an LDO regulator with output current capability of 0.1A. The output voltage is 12.0V with ±1% accuracy. The SOT89-3K package is most suitable for heat dissipation. As protective function to prevent IC from destruction, this chip has built-in over current protection circuit to protect the device when output is shorted, and built-in thermal shutdown circuit to protect the IC during thermal over load conditions. This product can be used in wide variety of digital appliances. This regulator can use ceramic capacitor, which have smaller size and longer life than other capacitors.
