LMV7291MGX from Texas Instruments, in a SC-70-5. 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	VOUT	output	Push-pull comparator output with CMOS stage giving rail-to-rail output swing; input/output pin voltages are limited to V+ +0.1V and V- -0.1V absolute maximum.
2	GND	power_in	Negative supply pin (V-), used as the 0V reference in all characterization conditions; absolute maximum supply voltage V+ to V- is 5.5V.
3	+IN	input	Non-inverting comparator input with rail-to-rail bipolar input stage; common-mode range is -0.1V below V- to 0.1V above V+, and VCM should be kept away from the ~950mV NPN/PNP crossover point.
4	-IN	input	Inverting comparator input with the same common-mode range of -0.1V below V- to 0.1V above V+ as the non-inverting input.
5	V+	power_in	Positive supply pin; the device is characterized at 1.8V, 2.7V and 5.0V with an absolute maximum supply voltage of 5.5V, and a 0.1uF bypass capacitor should be placed adjacent to it.
