BA05FP-E2

ROHM Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

BA05FP-E2 from ROHM Semicon, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in Input supply pin, with a recommended input voltage of 6 V to 25 V for the BA05 and an absolute maximum power supply voltage of 35 V; a 0.33 µF bypass capacitor should be placed as close as possible between this pin and GND.
2 GND power_in Ground reference pin for the regulator; the output capacitor (22 µF recommended) and the input bypass capacitor (0.33 µF) are returned to this pin.
3 OUT power_out Regulated 5 V output (4.75 V to 5.25 V) with a maximum output current of 1 A; a capacitor of 22 µF is recommended between OUT and GND to prevent oscillation.
