# CJ6376A50M

**Changjing** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

CJ6376A50M from Changjing, in a SOT-23-3L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VSS | power_in | Device ground reference. Connect to system ground / 0V return. |
| 2 | VOUT | power_out | Regulated 5.0V output. Delivers up to 300mA continuous with typical dropout ~200mV at 100mA. Requires ≥1.0µF output capacitor for stability. |
| 3 | VIN | power_in | Unregulated supply input, 2.5V to 36V (absolute max 40V). Requires ≥1.0µF input capacitor. |

## CAD (KiCad official)

- Symbol: `CJ6376A50M`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3L (KiCad packages3D, STEP)
- 3D model files: `cj6376a50m-etched.step` / `cj6376a50m-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cj6376a50m.step` / `cj6376a50m.glb` are the bare package body.
