# CJ6330B50M

**Changjing** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

CJ6330B50M 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 | IN | power_in | Input to the device; the recommended input capacitor should be placed as close to the IN and GND pins as possible for the best transient response and minimum input impedance. Input voltage range is 2.5 V to 18 V. |
| 2 | GND | power_in | Regulator ground. |
| 3 | EN | input | Enable pin: drive high to enable the device and low to turn it off; do not float this pin, and if not needed connect EN to IN. |
| 4 | NC | unconnected | No internal connection; this pin can float, but connecting it to GND gives better thermal performance. |
| 5 | OUT | output | Regulator output; an output capacitor must be placed between OUT and GND, as close as possible to those pins, to maintain stability and obtain the best transient response. |
