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

What is the function of the NC pin in the SNT-6A(H) package?

The NC pin is electrically open and can be connected to either the VIN pin or the VSS pin.

How does the ON/OFF pin control the regulator?

Setting the ON/OFF pin to the OFF level stops internal circuit operation and turns off the output transistor, significantly reducing current consumption.
