MST5650BTS 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; the input and output capacitors must connect between VIN/VOUT and GND, and a wide copper trace is required for both VIN and GND.
2	VIN	power_in	Input pin with a 5V to 60V input voltage range, decoupled by a 1μF ceramic capacitor placed as close as possible to the device between VIN and GND.
3	VOUT	power_out	Output pin for the fixed output voltage, which needs a minimum 1μF ceramic output capacitor (X7R or X5R) placed as close as possible between VOUT and GND.
