Pinout
1. VOUT: This pin outputs the regulated voltage, which in this case is fixed at 5.0V.
2. GND: The ground pin is connected to the ground of the system.
3. VIN: This pin is where the input voltage is supplied. It must be higher than the desired output voltage plus the dropout voltage.
4. SD (Shutdown): This pin is used to enable or disable the regulator. When connected to a low voltage, the device enters a low-power shutdown mode.
5. NC (No Connect): This pin is not internally connected and typically has no function in the circuit design.
The LP2992 is designed for battery-powered devices due to its low quiescent current and low dropout voltage.
