LT1963AMPS8#PBF from Analog Devices, in a SO-8. 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	power_out	Regulated output that supplies the load and requires a minimum 10µF output capacitor to prevent oscillations.
2	SENSE/ADJ	input	On the adjustable LT1963A this is the ADJ error-amplifier input, internally clamped to ±7V, with 1.21V reference referenced to ground and 3µA bias current flowing into the pin (SENSE on fixed-voltage versions).
3	GND	power_in	Ground pin.
4	NC	unconnected	No connection.
5	SHDN	input	Shutdown input that turns the output off when pulled low, must be tied to IN if unused, and leaves the device in low-power shutdown if left unconnected (typical pin current 3µA).
6	GND	power_in	Ground pin.
7	GND	power_in	Ground pin.
8	IN	power_in	Input supply pin, rated ±20V, needing a 1µF to 10µF bypass capacitor if far from the main input filter capacitor, and protected against reverse input voltage.
