Voltage Reference FAQ

How does the SHDN pin function?

The SHDN pin is an active-low input that powers down the device to less than 20µA. An internal pull-up resistor enables normal operation if left unconnected, though external pulling high is recommended.

What are the capacitor requirements for stability?

An input capacitor of 0.1µF or larger is required near the VIN pin. The output requires a capacitor between 2.7µF and 100µF with low ESR to ensure stability and proper turn-on behavior.
