CJ6330A25P

Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L

CJ6330A25P from Changjing, in a SOT-89-3L. 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; per the AxxP pin table this is pin 1 for the CJ6330A25P variant, and the input voltage range is 2.5 V to 18 V.
2 IN power_in Input to the device with an input voltage range of 2.5 V to 18 V; place the recommended input capacitor as close to the IN and GND pins as possible for best transient response.
3 OUT power_out Regulator output set to the fixed 2.5 V version; an output capacitor must sit between OUT and GND, placed as close as possible to those pins, to maintain stability.
