# CJ6205B33M

**Changjing** · Linear Voltage Regulators (LDO) · SOT-23-5L

CJ6205B33M from Changjing, in a SOT-23-5L. 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 | VIN | power_in | Power input pin, operating input voltage range 2.0V to 6.0V (absolute maximum VSS+7V). |
| 2 | VSS | power_in | Ground pin. |
| 3 | CE | input | Chip enable pin, high level 1.5V to VIN enables the output and low level of 0.3V max (CE = VSS) shuts down with standby current of 0.1uA max. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output pin, up to 500mA output current with a 1uF ceramic output capacitor. |
