LMH6657MG 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	OUTPUT	output	Amplifier output, which can typically supply 80 mA into the load with a swing of about 1 V from either rail and is short-circuit protected.
2	V-	power_in	Negative supply; total supply voltage (V+ - V-) must be 3 V to 12 V (absolute maximum 12.6 V).
3	+IN	input	Noninverting input, whose common-mode range extends 0.5 V beyond V- and to 1.7 V from V+.
4	-IN	input	Inverting input of the voltage-feedback amplifier.
5	V+	power_in	Positive supply; total supply voltage (V+ - V-) must be 3 V to 12 V (absolute maximum 12.6 V).
