LM7824ACT

Introduction

The LM7824ACT voltage regulator is a three-terminal, adjustable and positive voltage regulator, mainly used in harsh industrial environments to ensure proper power and voltage regulation for the equipment. It can reduce the ripple on the power supply, prevent excessive current and damage, and protect the device from over-voltage. The LM7824ACT is most commonly used for applications that require medium to low current output and is used to convert unregulated voltage inputs from 12 to 24V DC into stable 5, 6, 8, 9, 12, or 15V DC outputs, allowing for adjustable and fixed voltage applications.

Application Fields

The LM7824ACT is used in many industrial applications and is the ideal choice for harsh environments that require multiple power requirements. The most common application of the LM7824ACT is in the automotive and industrial market. It can also be used in other applications such as UPS, aerospace and consumer electronics systems. Other applications include avionics, computer peripherals and industrial automation systems.

Working Principle

The LM7824ACT is based on the linear voltage regulator principle. The voltage regulator works by providing a constant output voltage despite changes in input voltage or load current demands. The regulator module uses a reference voltage, typically 5V, and compares it to the input voltage. If the input voltage is higher than the reference voltage, then the regulator module provides ground connection to decrease the voltage to the output voltage. It also has an internal circuit which provides current limiting, overvoltage protection and thermal shutdown protection.

Features

The LM7824ACT voltage regulator offers a wide input range of between 12V to 24V DC and an adjustable output voltage of between 5V and 15V DC. This high power voltage regulator can support up to 2 Amps of output current and its internal current limit circuit ensures protection against overloads. It also features ripple rejection of 44dB and line regulation of 0.02%. It has a temperature range of -40°C to +85°C and a standard SOT-223 surface mount package. In addition, it has an advanced high current integrated circuit design which allows for better thermal resistance.
