HT7540-2-MS from MSKSEMI, 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 reference pin of the linear regulator. |
| 2 | VIN | power_in | Regulator input pin; the series is stated to withstand voltage up to 30V. |
| 3 | VOUT | power_out | Regulated output pin, 4.0V for HT7540-2-MS, with output voltage accuracy of ±1%, rated for up to 100mA output current. |
