SL7333-3 from Slkor SLKORMICRO Elec, in a SOT-23-3. 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 of the SOT23-3 package, listed as 地 (ground) in the pin description table. |
| 2 | VIN | power_in | Power input pin; recommended input voltage is +2.5 to +45 V, and the absolute maximum input voltage is 0 to +45 V (Note 1). |
| 3 | VOUT | power_out | Regulated output pin, which must be connected to ground through a capacitor greater than 1 uF; output current is 0 to 300 mA. |
