Working Principle

The NCV8161AMX300TBG works on negative voltage regulator principle. This type of regulator utilizes a P-channel MOSFET as the main switch and is connected in series with the output voltage source. The voltage drop across this series MOSFET is regulated by a reference voltage provided by an external resistor divider. The reference voltage is compared to the output voltage. If the output voltage is higher than the reference voltage, the negative voltage regulator will switch off the MOSFET and in turn reduces the dissipation.

When the output voltage is lower than the reference voltage, the MOSFET will be switched on, thus allowing the output voltage to rise until it reaches the reference voltage. For a given load current, the voltage drop across the series MOSFET will be directly proportional to the output voltage. This voltage drop is called dropout voltage. If the output voltage is regulated accurately, then the dropout voltage will remain constant.
