BA50DD0T

ROHM Semicon · Linear Voltage Regulators (LDO) · TO-220-3

BA50DD0T from ROHM Semicon, in a TO-220-3. 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 Power supply voltage input; recommended 3.0V to 25.0V for BAxxDD0xx, with a capacitor greater than 0.33µF to GND.
2 GND power_in Ground terminal (N.C./GND pin is GND on TO220FP-3); keep set ground and IC ground at the same potential.
3 OUT power_out Voltage output (5.0V for BA50DD0T, up to 2A); requires an anti-oscillation capacitor between Vo and GND.
