Voltage Regulators - DC DC Switching Regulators FAQ

What is the function of the ON/OFF pin?

The ON/OFF pin controls the regulator's operation. Connecting it to ground enables the circuit, while applying a high voltage disables it, reducing standby current.

How is the output voltage adjusted?

The output voltage is set using an external resistor divider network connected to the FEEDBACK pin, allowing adjustment between 1.23V and 37V.
