Working Principle of LD1086V25

LD1086V25 works on the principle of voltage regulation. It works by outputting a specific voltage in proportion to the input voltage. In order to achieve this, LD1086V25 is a low-dropout (LDO) voltage regulator, meaning that it can still provide the rated output voltage when the input voltage is very close to the output voltage.

The internal MOSFET acts as the pass element of the regulator, whose on-resistance varies with the load current to maintain the accurate output voltage. The voltage drop between the input voltage and output voltage is called the dropout voltage, which the LDO provides in a very low value.

LD1086V25 has an additional circuit which is connected in parallel to the pass element. This circuit is designed to reduce the power dissipation in the MOSFET. This circuit also has a few limitations, as it is not efficient below a certain load current. Therefore, the LD1086V25 should not be used to drive loads below 200mA.
