SL7333-8 from Slkor SLKORMICRO Elec, in a SOT-89-3. 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 | Ground pin (地), the common return for the regulator. |
| 2 | VIN | power_in | Power input pin; the datasheet gives a recommended input range of +2.5 V to +45 V and an absolute maximum input voltage of 45 V (0 to +45 V rating), with a polarized 1 uF to 10 uF input capacitor recommended close to the pin. |
| 3 | VOUT | power_out | Regulated output pin, which must have a capacitor of more than 1 uF connected to ground; the datasheet recommends a polarized 1 uF to 10 uF output capacitor with ESR of 5 to 100 mΩ. |
