**Corebai Microelectronics** · Linear Voltage Regulators (LDO) · SOT-223-3

CBM1117C-5.0 from Corebai Microelectronics, in a SOT-223-3. 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 | ADJ/GND | power_in | Adjust pin for the adjustable output option and ground pin for fixed-output options such as the 5.0V CBM1117C-5.0. |
| 2 | INPUT/OUTPUT | power_out | Listed as the regulator input voltage pin / regulator output voltage pin (I/O); the output needs a capacitor to ground (10uF tantalum minimum recommended) and the package case is electrically connected to the output. |
| 3 | INPUT | power_in | Regulator input voltage pin, maximum input voltage 15V, with a 10uF tantalum bypass capacitor recommended. |
