BAJ2CC0T

ROHM Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220-3

BAJ2CC0T 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 operating range 4.0V to 25.0V for BAxxCC0xx, 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 Fixed 12.0V voltage output for BAJ2CC0T, up to 1A, requiring an anti-oscillation capacitor between OUT and GND.

CAD (KiCad official)

  • Symbol: BAJ2CC0T
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220-3 (KiCad packages3D, STEP)
  • 3D model files: baj2cc0t-etched.step / baj2cc0t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); baj2cc0t.step / baj2cc0t.glb are the bare package body.
