LT1963ES8#TRPBF 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 pin, rated ±20V maximum, supplying up to 1.5A and stable with output capacitors as low as 10µF.
2 SENSE/ADJ input SENSE input for the fixed-voltage LT1963-1.5/-1.8/-2.5/-3.3 parts (±20V max) or ADJ feedback input for the adjustable LT1963 with a 1.21V reference (±7V max).
3 GND power_in Ground pin.
4 NC unconnected No connection.
5 SHDN input Shutdown input, rated ±20V maximum, that reduces quiescent current to <1µA when pulled low.
6 GND power_in Ground pin.
7 GND power_in Ground pin.
8 IN power_in Unregulated supply input, rated ±20V maximum, with reverse battery protection.
