# CJ6205A33M

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

CJ6205A33M 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 | Ground reference for the regulator. Connect to system ground. |
| 2 | VOUT | power_out | Regulated 3.3 V output pin (VOUT ±2% typ.). Requires a 1 μF ceramic output capacitor to VSS for stability. Rated up to 500 mA typ. with 150 mV dropout at 150 mA. |
| 3 | VIN | power_in | Unregulated power input, 2.0-6.0 V operating range (abs max VSS-0.3 to VSS+7 V). Decouple with a 1 μF ceramic capacitor to VSS. |
