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. |
