MST52L40BTS from MST, 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 | System ground pin for the regulator. |
| 2 | VIN | power_in | Input pin; the datasheet gives an input voltage range of 3V to 24V, with an absolute maximum VIN to GND of 30V. |
| 3 | VOUT | power_out | Output pin; the maximum output current is 150mA and the absolute maximum VOUT to GND is 12V. |
