Working Principle

The MC78M05CDT is a linear voltage regulator that utilizes the principle of closed loop feedback to adjust and maintain the output voltage. The device uses an error amplifier that monitors the difference between the output and the reference voltage. When the error amplifier detects a discrepancy, it will adjust the output voltage of the device, either increasing or decreasing it, until the desired voltage is reached. This allows the device to compensate for undesirable factors such voltage drops due to resistor deviation or capacitance. The MC78M05CDT also includes several protection features that can prevent potentially damaging conditions. It includes both over-temperature, over-current and over-voltage protection, which can prevent the device from being damaged during high loading conditions. Additionally, the device also show good thermal performance and transient response.
