Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3L
CJ75L033S 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 3.3V output, up to 300 mA. Requires an output capacitor between OUT and GND, placed as close to the pin as possible for best transient response. |
| 2 | GND | power_in | Regulator ground reference. On SOT-89 this pin is fused to the die-pad tab and should be tied to a large ground copper for thermal dissipation. |
| 3 | IN | power_in | Unregulated input supply, 2.5V to 36V. Place a 1µF (or larger) input capacitor as close as possible to IN and GND to minimize input impedance and improve transient response. |
