BDXXFA1FP3 Datasheet, PDF (1/17 Pages) Rohm – High accuracy output voltage

100mA Fixed Output
LDO Regulator
BDxxFA1FP3
● General Description
BDxxFA1FP3 is an LDO regulator with output current capability of 0.1A. The output voltages are 3.3V, 5.0V, 5.4V, and
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.
