CJ6330B12M

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

CJ6330B12M 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 as possible to the IN and GND pins to obtain the best transient response and minimize input impedance.
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 connect EN to IN if the enable function is not needed.
4 NC unconnected No internal connection; this pin can float, but connecting it to GND gives the device better thermal performance.
5 OUT power_out Regulator output; place the recommended output capacitor between OUT and GND as close as possible to the pins to maintain stability and obtain the best transient response.
