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. |
