LT1797IS5#TRMPBF from Analog Devices, in a TSOT-23-5. 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	OUT	output	Rail-to-rail output swinging to within 50mV of V+ and 8mV of V-, driving loads up to 25mA with 25mA minimum short-circuit current at 5V.
2	V-	power_in	Negative supply (or ground in single-supply use); total supply V+ to V- is 2.7V to 12V (12.6V absolute max), bypassed with about 0.1µF when using split supplies.
3	+IN	input	Noninverting input with common mode range including both rails, phase reversal protection and internal protective resistors, with input current limited to ±10mA.
4	-IN	input	Inverting input with common mode range including both rails, phase reversal protection and internal protective resistors, with input current limited to ±10mA.
5	V+	power_in	Positive supply, with total supply voltage 2.7V to 12V (12.6V absolute max) and bypassed with about 0.1µF within an inch of the pin.
