Pinout

The TLV74328PDBVR is a low-dropout (LDO) voltage regulator from Texas Instruments. It is typically offered in a 5-pin SOT-23 package. Here is a brief overview of its pin count and functions:
1. Pin 1 (IN): The input pin where the unregulated voltage is supplied. It should be connected to a voltage source that is higher than the desired output voltage.
2. Pin 2 (GND): The ground pin, serving as the reference point for the regulator and connected to the system ground.
3. Pin 3 (EN): The enable pin, used to turn the regulator on or off. A high signal on this pin enables the device, while a low signal disables it.
4. Pin 4 (NC): No connection; this pin is generally not connected in the circuit design.
5. Pin 5 (OUT): The output pin where the regulated voltage is provided to the load. This pin delivers the stabilized output voltage.
The TLV74328PDBVR is designed for low quiescent current, making it suitable for battery-powered devices, and provides a fixed output voltage of 2.8V.
