Working Principle

The LP38691SDX-2.5 is a three-terminal linear regulator with an adjustable output voltage. It is designed for low voltage applications and is floating with respect to the input supply. The part is adjustable from 0.8V to 5.0V. A separate reference pin is used to set the output voltage.

The device operates by regulating the output voltage at the SET pin. When the output voltage deviates from the reference voltage at the SET pin, the device responds with a correction current. This current is fed through a reference resistor, connected between the OUT and SET pins, allowing the regulator to adjust its output voltage until the reference voltage is met.

The LP38691SDX-2.5 is protected against under-voltage, output short-circuit protection and excessive temperature limits. Additionally, the device has a power-on reset period during which the output voltage is ramp-up slowly, allowing the device and the system to power up safely.
