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

What is the purpose of the NC pin on the W-DFN2020-6 package?

The NC pin is not connected internally but should be tied to GND to maximize PCB copper area for improved thermal dissipation.

How does the device behave when disabled?

When the EN pin is pulled low, the regulator enters shutdown mode and activates an internal auto-discharge resistor to safely drain the output voltage.
