Working Principle

The linear voltage regulator is the most basic type of voltage regulator. It maintains a constant output voltage for a given input voltage, by adjusting the current supplied to the load in order to stabilise the output voltage. The regulator works by controlling the amount of current that is allowed to be drawn from the input voltage supply. This is done by measuring the output voltage and comparing it to a reference voltage. If the output voltage is lower than the reference voltage, the regulator will increase the current flow to the output, and if the output voltage is higher than the reference voltage, the regulator will decrease the current flow. This process is repeated continuously in order to maintain a stable output voltage.

The MC78M20CTG is a monolithic, linear voltage regulator that maintains a constant output voltage over a wide range of input voltages. It is designed to provide a maximum output current of 5.0 A and has two output voltage options: adjustable and fixed. The adjustable output voltage can be set using two external resistors, while the fixed output voltage option offers two different output voltages. The regulator also features a wide temperature range of -40°C to + 125°C and excellent load and line regulation.
