LM7824T +24V Voltage Regulator

Overview

The LM7824T is a positive voltage regulator from Taejin that provides a fixed +24V output from a positive input voltage. Compatible with the LM78xx series of positive linear voltage regulators.

Key Specifications

  • Output Voltage: +24V ±4%
  • Input Voltage Range: 26.5V to 35V
  • Maximum Output Current: 1A
  • Package: TO-220 (3-pin)
  • Dropout Voltage: 2.5V typical
  • Operating Temperature: 0°C to 125°C

Applications

  • 24V motor driver power supplies
  • Industrial control systems
  • High-voltage LED drivers
  • Stepper motor controllers
  • 24V sensor power supplies

Features

  • Fixed +24V output
  • Internal thermal overload protection
  • Internal short circuit current limiting
  • Output transistor safe area protection
  • No external components required
  • Standard LM78xx pinout

Usage Notes

  • Requires adequate heat sinking for all current levels due to high voltage drop
  • Input capacitor (0.33µF) recommended if regulator is far from filter capacitor
  • Output capacitor (0.1µF) improves transient response
  • Minimum load current: 5mA for proper regulation
  • High power dissipation - calculate heat sink requirements carefully

Power Dissipation

With 30V input and 1A output:

  • Power dissipated = (30V - 24V) × 1A = 6W
  • Requires substantial heat sinking
