SETOV

Regulated Output-Voltage Selector. Connect SETOV to OUT for a 5V fixed output, or connect

SETOV to GND for a 3.3V fixed output. SETOV becomes the feedback path when using an

external resistive divider for an adjustable output. If SETOV pin driven externally, 1kΩ resistor in

series is required.

OUT

Regulator Output. Bypass OUT to GND with a minimum of 2.2μF. Use a low-ESR, ceramic

capacitor (X7R, X5R) for optimal performance. The SETOV input controls the output voltage when

in fixed +3.3V or fixed +5V output-voltage mode. Using an external resistive divider between OUT

and SETOV sets adjustable output voltage from +0.6V to +11V.
