Working Principle

The L78M05T-TR-E is a 3-terminal positive voltage regulator that works on the principle of a voltage divider. The voltage divider comprises of two resistors, one of which is the shunt, that controls the output voltage. The device utilises an internal voltage reference to control the output voltage. A feedback loop is utilised in order to control the output voltage by varying the current through the series resistor. This current flow is then regulated by adjusting the voltage across the shunt. The output voltage is thus kept at the desired level by controlling the current flow through the resistors.

The L78M05T-TR-E regulator is a versatile device that can be used in a variety of applications due to its wide output voltage range, high accuracy and low output noise. It is also capable of delivering up to 1.5 A output current while maintaining a wide input voltage range and low dropout voltage. The device also offers over-temperature protection (OTP), line and load regulation of 0.1% and low noise output voltage of less than 10 µVrms.
