CJ78L05C-P3T-ARG

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

CJ78L05C-P3T-ARG from Changjing, in a SOT-89-3L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT power_out Regulated 5.0V output of the regulator. Typical accuracy is ±3% at TJ = 25°C (4.85V to 5.15V) and ±5% over the full temperature range. Delivers up to 100mA; a 0.1µF output capacitor is recommended for stability.
2 GND power_in Regulator ground reference. All output and input voltages are measured with respect to this terminal.
3 IN power_in Unregulated input supply to the regulator. Recommended input voltage range for the 5.0V variant is up to 30V (absolute max 36V). A 0.33µF input capacitor is recommended when the device is far from the power-supply filter.
