Changjing · Linear Voltage Regulators (LDO) · SOT-89-3L
CJ6385A50P 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. |
| 2 | IN | input | Input to the device; use the recommended value of the input capacitor and place it as close to the input of the device as possible to reduce the impedance of the input supply. |
| 3 | OUT | output | Output of the regulator; an output capacitor is required for stability and to help the device obtain the best transient response, and it should be placed as close as possible to the output. |
