Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the function of Pin 3 (Enable)?

Pin 3 is the Enable input used to place the device into low-power standby mode. Pulling this pin low disables the regulator, while pulling it high turns it on. If unused, it should be connected to Vin.

Does the NCP612SQ27T2G require a minimum load current?

No, the device is stable without a minimum output current and does not require specific Equivalent Series Resistance (ESR) values for the output capacitor.
