ME6118A33PG from MICRONE, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	GND	power_in	Ground reference for the LDO. Connect to the system ground plane; also acts as the thermal path via the package tab on SOT-89.
2	VIN	power_in	Unregulated input supply, 2.5V to 18V (absolute max 18V). Requires a 10uF input capacitor (CIN) to ground close to the pin. Must be at least VOUT + dropout (≈ 3.3V + 0.68V @ 800mA) for regulation.
3	VOUT	power_out	Regulated 3.3V output, capable of >1A (typ 800mA IOUTMAX spec). Requires a 10uF output capacitor (COUT) to ground for stability. Internally current-limited to ~1.1A and thermal-shutdown protected.
