Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ
How does the Enable pin function?
The EN pin turns the regulator on when driven high and puts it into shutdown mode when pulled low. It must not be left floating during operation.
What is the purpose of the NC pin?
The NC pin is internally unconnected. It is recommended to connect it to GND on the PCB to maximize copper area for better thermal dissipation.
