Pinout
1. VIN (Pin 1): This is the input voltage pin where the unregulated input voltage is supplied.
2. GND (Pin 2): This is the ground pin, serving as the common ground path for the input and output voltages.
3. EN (Pin 3): The enable pin is used to turn the regulator on or off. Pulling this pin high enables the output, while pulling it low disables it.
4. NC (Pin 4): This is a no-connect pin, which means it is not internally connected and can be left floating or connected to ground.
5. VOUT (Pin 5): This is the output voltage pin, providing the regulated output voltage of 1.8V.
The TPS78218DDCR is designed for ultra-low power applications, offering low quiescent current and fast transient response, ideal for use in battery-powered devices.
