Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L
CJ6330A30P 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; the datasheet gives no further electrical limit for this pin. |
| 2 | IN | power_in | Input to the device, with a input voltage range of 2.5V to 18V; place the recommended input capacitor as close to the IN and GND pins as possible for the best transient response and minimum input impedance. |
| 3 | OUT | power_out | Output of the regulator; an output capacitor must be placed between OUT and GND, as close as possible to the pins, to maintain output stability and obtain the best transient response. |
