Working Principle of LP2985AIBPX-5.0/NOPB

The LP2985AIBPX-5.0/NOPB voltage regulator works in the following way. Its input voltage is applied directly to the P-channel MOSFET (PMOS) at the input of the IC, which reduces the voltage to the desired output voltage by increasing or decreasing the gate-source voltage. As the output voltage is maintained in an active low-dropout state, the input voltage must remain above the dropout voltage for the IC to continue functioning. This is facilitated by an internal reference voltage of 1.25V, which is compared with the incoming input voltage. If the input voltage drops below the reference voltage, the PMOS will be disabled and the output voltage will fall to zero.

In addition to the PMOS, the IC is also equipped with a voltage protection circuit to prevent overvoltage conditions. When an overvoltage condition is detected, the protection circuit will limit the output voltage to a safe level. In addition, the IC is also outfitted with a thermal protection feature, which will turn off the output if the temperature of the IC exceeds a certain safe level. This feature helps protect the IC from damage due to overheating.
