Package

The LM7824CT is a voltage regulator with a TO-220 package type. This package includes three pins and a metal tab for heat dissipation, commonly used for linear voltage regulators.

Pinout

The LM7824CT is a voltage regulator integrated circuit with a pin count of three. It is part of the 78xx series of fixed linear voltage regulators. The "24" in its name indicates that it outputs a regulated 24V DC voltage.
The pin functions are as follows:
1. Input (Pin 1): This is where the unregulated input voltage is applied. The input voltage must be higher than the desired output voltage (typically by at least 2-3 volts).
2. Ground (Pin 2): This is the common ground pin for both the input and output voltage. It is connected to the common ground of the circuit.
3. Output (Pin 3): This pin outputs the regulated 24V DC voltage. It is where the stabilized voltage is supplied to the load.
The LM7824CT typically provides up to 1.5A of output current. It is equipped with internal current limiting, thermal shutdown, and safe area protection, making it robust and reliable for various applications.
