The L7824ACV is a reliable three-terminal voltage regulator IC for regulating the output voltage of common fixed output linear power supplies. It is designed with a low power dissipated, low dropout voltage, low cost, and low noise, making it ideal for a wide range of applications, including automotive, audio, power management, and computer, among others. The regulator is based on a linear regulating principle, with a transistor and circuit to ensure a steady output voltage even under a wide range of load and temperature variations. The voltage regulator is available in a variety of configurations and packages, allowing for greater flexibility and efficiency, when compared to other regulators.The L7824ACV is a three-terminal voltage regulator; it contains an error amplifier, voltage reference, an output voltage divider, a Schottky diode, and a current-limiting circuit. The regulator is designed with a common emitter amplifier, which increases the transconductance of the output transistor to regulate the output voltage. The voltage regulator sets the output voltage to a preset value regardless of changes in output load, line voltage, or temperature.The output voltage is specified by the voltage divider, which connects one end of the sensing resistor to the output terminal and the other end of the resistor to the adjoint pin. The adjoint pin of the L7824ACV allows for an adjustable output voltage for external adjustment capabilities. The output transistor is typically composed of MOSFET, N-channel Jfet, or P-channel Jfet. The current-limiting circuit is used to protect the power supply from overload conditions, which may occur due to the excessive current passing through the output terminal. The current-limiting circuit is composed of a MOSFET, N-channel Jfet, and P-channel Jfet. If a short or open circuit is detected at the output, the current-limiting circuit is triggered and the output voltage is forced to 0V.The Schottky diode is usually connected between the input and output terminals, to prevent reverse current flowing across the regulator. The diode additionally prevents motor noise, or high frequency signals, from causing the voltage regulator to oscillate.The L7824ACV is widely used in a number of applications requiring a stable, adjustable output voltage. The voltage regulator is commonly used automotive, computer, audio, power management, and other applications where a low cost, low noise, and low power rating is required. The output voltage of the L7824ACV can be adjusted from 0V to 17V, depending on the number of resistors and capacitors connected to the adjoint pin. The dropout voltage is typically between 0.5V and 1.5V.
