Description

The LM7824CT is a fixed-voltage linear voltage regulator that outputs a stable 24V DC. Part of the popular 78xx series of regulators, it is designed to provide a simple and efficient solution for applications requiring a regulated power supply. The "CT" suffix indicates a TO-220 package, which is a common form factor for power components, allowing easy mounting and heat dissipation.
Key features of the LM7824CT include:
1. Output Voltage: 24V with a maximum output current of 1.5A.
2. Input Voltage: Typically requires an input voltage at least a few volts higher than 24V to maintain regulation.
3. Thermal Protection: Integrated thermal shutdown to prevent overheating.
4. Short-Circuit Protection: Built-in current limiting to safeguard against overcurrent conditions.
5. Voltage Regulation: Good line and load regulation, ensuring a stable output despite variations in input voltage or load current.
The LM7824CT is widely used in electronics to power devices that require a stable 24V power supply, making it a versatile choice for hobbyists and professionals alike.

Equivalent

The LM7824CT is a positive voltage regulator that provides a fixed output of 24V. Equivalent products include the L7824CV and UA7824CKT. Other compatible alternatives are the MC7824CT and the KA7824, which offer similar specifications in terms of voltage output and current capabilities. However, always check the datasheets for pin configuration and thermal characteristics to ensure compatibility.

Features

The LM7824CT is a fixed-voltage linear voltage regulator from the 78xx series, designed to provide a stable +24V output voltage. Key features include:
1. Output Voltage: Fixed at 24V with a typical output current capability of 1A, though it can handle higher currents with proper heat dissipation.
2. Input Voltage Requirement: Requires a minimum input voltage of around 26V to maintain regulation.
3. Thermal Protection: Includes internal thermal overload protection to prevent damage from excessive heat.
4. Short-Circuit Protection: Provides current limiting and short-circuit protection to safeguard the device and the load.
5. Dropout Voltage: Typically around 2V, meaning the input voltage must be at least 2V higher than the 24V output to maintain regulation.
6. Package: Often available in a TO-220 package, suitable for mounting with a heatsink to improve thermal performance.
7. Ripple Rejection: Offers good ripple rejection, reducing the effects of input voltage variations.
These features make the LM7824CT suitable for various applications requiring a reliable 24V power supply.

Pinout

The LM7824CT is a voltage regulator from the LM78xx series, which provides a fixed output voltage. Specifically, the LM7824CT outputs a stable 24V DC. It typically comes in a TO-220 package with three pins:
1. Input (Pin 1): This pin receives the unregulated input voltage, which should be higher than 24V to ensure proper regulation.
2. Ground (Pin 2): This is the common ground pin for both the input and output voltages. It serves as a reference point for the circuit.
3. Output (Pin 3): This pin provides the regulated 24V output.
The LM7824CT is designed to deliver up to 1.5A of output current, provided that the input voltage is sufficiently higher than the output voltage and an adequate heat sink is used to dissipate excess heat. This regulator is commonly used in power supply applications where a stable and reliable 24V output is required.
