LT1963ES8#PBF

Analog Devices · Linear Voltage Regulators (LDO) · SOIC-8

LT1963ES8#PBF from Analog Devices, in a SOIC-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 for ±20V on the pin, supplying up to 1.5A and stable with output capacitors as low as 10µF.
2 ADJ input Adjustable-version feedback pin (SENSE on fixed-voltage parts) with 1.21V reference voltage, pin voltage rated ±7V for ADJ.
3 GND power_in Ground pin.
4 NC unconnected No connect pin.
5 SHDN input Shutdown control input rated ±20V; pulling it low shuts the regulator down to <1µA quiescent current.
6 GND power_in Ground pin.
7 GND power_in Ground pin.
8 IN power_in Unregulated input supply pin, rated ±20V on the pin, with minimum input voltage of 2.5V at 1.5A load.
