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. |
