Description
One of its key features is its ultra-low quiescent current, typically around 3 µA, which is beneficial for battery-powered applications where power efficiency is critical. The regulator provides a fixed output voltage, with options typically available for 3.3 V or 5 V. It includes several protection mechanisms such as overcurrent protection, thermal shutdown, and reverse-battery protection, enhancing its reliability in harsh conditions.
The TPS7B4250QDBVRQ1's small footprint, combined with its robust performance characteristics, makes it an excellent choice for automotive systems requiring efficient power management, such as in infotainment systems and body electronics.

Pinout
1. IN (Pin 1): This is the input pin where the unregulated voltage is applied. It supports a wide input voltage range, making it suitable for automotive and industrial applications.
2. GND (Pin 2): This pin is the ground reference for the regulator. It should be connected to the system ground.
3. NC (Pin 3): This is a No Connect pin. It is not internally connected to the device and can be left floating or connected to ground for PCB layout purposes.
4. OUT (Pin 4): The regulated output voltage is available at this pin. It is used to power the load with the stable voltage provided by the regulator.
5. EN (Pin 5): This is the enable pin. It is used to turn the regulator on or off. When pulled high, the device is enabled, and when pulled low, the device is disabled.
The TPS7B4250QDBVRQ1 provides a fixed output voltage of 5V with a maximum output current of 50 mA.
