The MC78PC30NTR application field includes LED drivers, battery chargers, motor drivers and controls, power supplies and other applications in which precise control, low noise distortion, and reliability are required.

In order to achieve such performance, the MC78PC30NTR works on the linear voltage regulator principle. In this type of regulator, the output voltage is regulated by a voltage drop across an active component, usually a metal oxide field-effect transistor (MOSFET) or bipolar junction transistor (BJT).

The regulating component acts like a variable resistor and its resistance varies with the input supply voltage and the output load current in order to ensure that a constant voltage is maintained at the output.

In the MC78PC30NTR, a MOSFET is used as the regulating component. This MOSFET is driven by an error amplifier which compares the output voltage with a reference voltage and adjusts the MOSFET gate voltage accordingly. Thus, the MOSFET provides excellent regulation with tolerable levels of output noise, current limiting and thermal regulation.

The MC78PC30NTR is a very efficient and affordable voltage regulator, ideal for applications where precision power management is required. It features outstanding performance, low noise and thermal regulation, current limiting and output soundness protection.
