GP8101S-TC50-EW from Guestgood, in a ESOP-8. 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	NC	unconnected	No connect. Leave floating.
2	NC	unconnected	No connect. Leave floating.
3	PWM	input	PWM signal input. Accepts 0%-100% duty-cycle PWM at 50 Hz to 50 kHz; logic-high level 2.7 V to 5.5 V.
4	VCC	power_in	Supply voltage input. Operating range 9 V to 36 V (12 V typ). Quiescent current ~1.2 mA typ, 2 mA max at VCC=12 V no-load.
5	GND	power_in	Device ground reference.
6	VOUT	output	Analog voltage output. Delivers 0-5 V (SEL=GND) or 0-10 V (SEL=V5V) proportional to PWM duty cycle. Must be decoupled with a 0.1 uF capacitor to GND; short-circuit protection stops output when shorted to GND. Drive up to 20 mA (VOUT>0.5 V, VCC=12 V).
7	SEL	input	Output range select. Tie to GND for 0-5 V VOUT full scale; tie to V5V for 0-10 V VOUT full scale.
8	V5V	power_out	Internal 5 V LDO output. Requires an external decoupling capacitor greater than 1 uF to GND. Can source up to 5 mA (Icc_V5V); loading may slightly degrade output accuracy.
