NCP120AMX105TCG

PMIC - Linear voltage regulators, such as the NCP120AMX105TCG, are designed to ensure that electric loads receive clean and steady power within a specific level of voltage. The purpose of linear regulators is to create the ideal voltage from a source that can either be too low or too high. Linear voltage regulators are a type of electronic system typically used for power electric loads that require a certain level of voltage.

Working principle

Linear voltage regulators operate on a fixed-voltage regulation circuit. This means that incoming voltage is compared with the ideal voltage level and, if there is a discrepancy, the regulator will act to reduce or increase the voltage in order to return it to the ideal level.This regulation is achieved through the regulator\'s control element, which is typically comprised of a transistor. When additional voltage is needed, the transistor acts as a resistance and sinks the current and reduces the voltage to the ideal level. Similarly, a transistor that is open conducts current and increases the voltage when voltage is below the desired level.
