MST5633BTS 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 | Ground pin for the LDO; the datasheet recommends a wide copper trace for both VIN and GND and placing the input and output capacitors as close as possible to the device. |
| 2 | VIN | power_in | Input pin with an operating input voltage of 5V to 60V (absolute maximum VIN to GND of 80V), decoupled with a 1uF ceramic capacitor placed as close as possible to the device. |
| 3 | VOUT | power_out | Regulated output pin supplying up to 150mA with a fixed output of 3.0V, 3.3V, 3.6V or 5.0V, requiring a minimum 1uF ceramic output capacitor (X7R or X5R) placed close to VOUT and GND. |
