MEL7135PG-N from MICRONE, in a SOT-89. 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	VDD	power_in	Positive supply input. Operating range 2.7 V to 6.0 V (absolute max -0.3 V to +7 V). Typical quiescent supply current 90 uA.
2	GND	power_in	Ground / device return. Reference for VDD and OUT.
3	OUT	output	Constant-current sink output. Sinks a regulated current (350 mA typ for MEL7135, range 315-385 mA at VOUT=0.2 V) from the LED cathode to internal ground reference. Absolute max output voltage -0.3 V to +7 V; line regulation 1 mA/V typ over VDD 3-6 V.
