FAQ

Is an external capacitor required for circuit stability?

No, the ADR392 does not require external capacitors for stability under any load condition, though a 0.1 μF ceramic capacitor is recommended to absorb dynamic load charge.

How is the shutdown pin configured if the feature is unused?

If the shutdown feature is not used, the SHDN pin must be connected directly to the VIN pin.
