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

What is the function of the NC pin on the SOT-89-5 package?

The NC pin is electrically open and can be connected to the VIN pin or the VSS pin if necessary for mounting purposes.

How does the ON/OFF pin operate for the 'B' type product?

For the 'B' type, setting the ON/OFF pin to a high level activates the regulator, while a low level stops operation and reduces current consumption.
