SK6216CMMR-33 from Suntek, in a SOT-23. 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, the reference for the regulator. |
| 2 | VOUT | power_out | Regulated output pin, rated for up to 500mA output current with output voltage tolerance of ±2% at 1.0mA to 30mA load. |
| 3 | VIN | power_in | Input voltage pin, with input voltage range of 3.5V to 15V per the electrical characteristics. |
