CJ6330A30M

Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

CJ6330A30M from Changjing, in a SOT-23-3L. 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 GND power_in Regulator ground.
2 OUT power_out Regulator output; an output capacitor must be placed between OUT and GND to maintain stability, as close to the OUT and GND pins as possible for best transient response.
3 IN power_in Input to the device; use the recommended input capacitor placed as close as possible to the IN and GND pins to obtain the best transient response and minimize input impedance. Input voltage range is 2.5V to 18V.
