# CJ6206A28N

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

CJ6206A28N from Changjing, in a SOT-23. 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 | Ground reference for the regulator. Connect to system ground; low-ESR ceramic bypass caps on VIN and VOUT return here. |
| 2 | VOUT | power_out | Regulated output pin, fixed 2.8V (±2% typ.), rated 300mA (600mA abs. max.). Requires a 1µF low-ESR ceramic output capacitor to ground for stability. |
| 3 | VIN | power_in | Unregulated power input, 2.0V-7.0V operating range (abs. max VSS-0.3 to VSS+8V). Bypass with a 1µF low-ESR ceramic capacitor to VSS close to the pin. |

## CAD (KiCad official)

- Symbol: `CJ6206A28N`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `cj6206a28n-etched.step` / `cj6206a28n-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cj6206a28n.step` / `cj6206a28n.glb` are the bare package body.
