Working Principle of LP2985-25DBVT

The working principle of the LP2985-25DBVT is based on the classic linear regulator topology. It consists of a series pass transistor, a differential amplifier and a control loop. The series pass transistor is used to regulate the output voltage, which is set by the control loop. The differential amplifier detects the difference between the reference and output voltage. The control loop then drives the series pass transistor to reduce the differential voltage.

The output voltage is determined by a voltage divider consisting of two resistors. The input voltage is applied to the divider, while the output voltage is taken from the junction of the two resistors. The control loop adds current to the base of the series pass transistor, controlling the output voltage of the regulator.
