Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Regulator output that supplies the load and requires a minimum 3.3µF output capacitor to prevent oscillation, with larger capacitors needed for large transient loads. |
| 2 | SENSE/ADJ | input | On the LT1763-5 fixed-output part this is the SENSE input to the error amplifier, best connected to OUT at the load; it can be pulled below ground in dual-supply systems and still allow start-up and operation. |
| 3 | GND | power_in | Ground pin; connect the bottom of the output voltage setting divider directly to the GND pins for optimum load regulation. |
| 4 | BYP | passive | Bypass pin clamped internally to ±0.6V; a capacitor of up to 0.01µF from OUT lowers output noise to a typical 20µVRMS over 10Hz to 100kHz, and the pin must be left unconnected if not used. |
| 5 | SHDN | input | Shutdown pin where the output turns off when pulled low, driven by 5V logic or open-collector logic with a pull-up resistor, and it must be connected to IN if unused. |
| 6 | GND | power_in | Ground pin; connect the bottom of the output voltage setting divider directly to the GND pins for optimum load regulation. |
| 7 | GND | power_in | Ground pin; connect the bottom of the output voltage setting divider directly to the GND pins for optimum load regulation. |
| 8 | IN | power_in | Power input with a wide 1.8V to 20V input range, where a 1µF to 10µF bypass capacitor is recommended if the device is more than six inches from the main input filter capacitor. |
