Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L
CJ6330B36M 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; place the recommended input capacitor as close to IN and GND as possible for the best transient response and minimum input impedance, with an input voltage range of 2.5V to 18V. |
| 2 | GND | power_in | Regulator ground for the device. |
| 3 | EN | input | Enable pin: drive high to enable and low to turn the device off, do not float this pin, connect it to IN if not needed, and keep the enable input voltage within -0.3V to 24V. |
| 4 | NC | unconnected | No internal connection; this pin can float, but connecting it to GND gives better thermal performance. |
| 5 | OUT | power_out | Regulator output; place an output capacitor between OUT and GND as close as possible to the pins to maintain stability and obtain the best transient response. |
