LK7533-M from LANKE, 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 | VSS | power_in | Ground pin (VSS/GND) of the regulator, shared by the reference and output divider. |
| 2 | VIN | power_in | Regulator input supply; input voltage range up to 30V (absolute max 36V), with 1-10uF capacitor to GND recommended. |
| 3 | VOUT | power_out | Fixed 3.3V regulated output (±2%) delivering up to 150mA, with 1-10uF capacitor to GND recommended. |
