MC7905ACD2T - Linear Voltage Regulators Application Field and Working Principle

The MC7905ACD2T series of windings are linear voltage regulators that are commonly used in applications requiring low voltage regulation, high input voltages, extremely low noise and low power output voltage. The MC7905ACD2T series of linear voltage regulators deliver reliable performance at an outstanding price. They have a wide input voltage range of 2.7V to 24V, with adjustable output ranges from 5V to 18V, making them suitable for a wide variety of applications.

They offer outstanding thermal stability, low noise, and low power dissipation. Their no-load operational characteristics provide a good input/output linearity, and the monolithic construction is tolerant to RF interference. They are primarily used for regulating voltage in low-impedance loads.

Functionality

The MC7905ACD2T linear voltage regulators provide voltage regulation between the output and the input, or ground. The MC7905ACD2T series of linear voltage regulators are designed to provide a regulated output voltage that is precisely equal to the nominal voltage of the regulator. This is done by controlling the amount of current that flows through the power stage of the regulator.

The MC7905ACD2T series of linear voltage regulators consist of two building blocks: the error amplifier, and the power stage. The error amplifier is a voltage-controlled differential amplifier that monitors the voltage at the output of the regulator, and compares it to that of an internal reference voltage. The power stage consists of a current-controlled power source, and an adjustable resistor that controls the amount of current that is supplied to the output pins.
