Pinout
The pin functions are as follows:
1. IN (Pin 1): This is the input voltage pin where the supply voltage is applied.
2. GND (Pin 2): This pin is connected to the ground.
3. EN (Pin 3): This is the enable pin. The regulator is turned on when this pin is connected to a high logic level and turned off when connected to a low logic level.
4. NC (Pin 4): This pin is not connected internally and is typically used for mechanical support.
5. OUT (Pin 5): This is the output voltage pin where the regulated voltage is supplied.
The device is designed for ultra-low power applications, providing a fixed output voltage of 3.0V in the case of the TPS78230 variant.
