Working Principle

The LP38692SDX-2.5/NOPB is a low power linear regulator that uses the feedback principle to regulate the output voltage. The device utilizes an internal error amplifier that compares the output voltage to an internally-generated reference voltage. The output voltage is adjusted by controlling the gate voltage of the pass transistor, which varies the current through the load. When the load varies, the device will adjust the output voltage to maintain the set output level.The LP38692SDX-2.5/NOPB features over-current protection to keep the output current from exceeding its rated limits. When the current exceeds the set threshold, the device will shut off the output and the output voltage will drop significantly.

Conclusion

The LP38692SDX-2.5/NOPB is a low power linear regulator designed for a wide range of applications. It offers a wide input voltage range, high efficiency over-current protection, and fast transient response to meet the needs of automotive, consumer, and computer applications. The device utilizes a feedback principle to regulate the output voltage and features over-current protection to keep the output current from exceeding its rated limits. With its wide operating temperature range and low quiescent current, the LP38692SDX-2.5/NOPB is perfectly suited for use in mobile applications and other low power systems.
