Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Output supplies power to the load and requires a minimum 3.3µF output capacitor to prevent oscillations, with larger capacitors needed for large transient loads. |
| 2 | SENSE/ADJ | input | For fixed-voltage versions this is the SENSE input to the error amplifier, which should be connected to OUT for optimum regulation; for the LT1763 it is the ADJ input, internally clamped to ±7V, with a 30nA bias current and a 1.22V reference. |
| 3 | GND | power_in | Ground; the bottom of the output voltage setting resistor divider should be connected directly to the GND pins for optimum load regulation. |
| 4 | BYP | passive | Reference bypass pin clamped internally to ±0.6V, where a maximum 0.01µF capacitor from OUT reduces output noise, and it must be left unconnected if not used. |
| 5 | SHDN | input | Shutdown input that turns the output off when pulled low, may be driven by 5V logic or open-collector logic with a pull-up resistor, and must be connected to IN if unused. |
| 6 | GND | power_in | Ground pin that must be connected to the other GND pins and the output divider bottom for proper load regulation. |
| 7 | GND | power_in | Ground pin that must be connected to the other GND pins and the output divider bottom for proper load regulation. |
| 8 | IN | power_in | Input supply pin that tolerates reverse voltage with respect to ground and OUT, and should have a 1µF to 10µF bypass capacitor if it is more than six inches from the main input filter capacitor. |
