# CJ6206A30N

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

CJ6206A30N 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 pin. Common return for input, output and internal reference. Connect directly to system ground. |
| 2 | VOUT | power_out | Regulated 3.0V output pin. Delivers up to 300mA (typ) with 150mV dropout at 150mA load. Requires a ~1uF low-ESR ceramic output capacitor for stability. |
| 3 | VIN | power_in | Unregulated input supply pin. Operating range 2.0V to 7.0V (absolute max VSS-0.3 to VSS+8V). Decouple with a ~1uF low-ESR ceramic capacitor to VSS. |
