LM7824 Description:
LM7824 is a positive voltage regulator IC manufactured in TO-220 package and also manufactured in other packages by some manufacturers. The IC provides accurate 24V at the output and capable to handle the maximum input voltage of 40V DC. The input voltage should be 2V to 3V higher than the ICs output voltage to get stable 24V output and the maximum input ampere should be 1.6 to 2 ampere to get 1.5A at the output. One of the advantage of these voltage regulator is that regardless the input voltage is fluctuating between the required input by the IC the output voltage will be remain the same and accurate. However the IC provides fixed output of 24V but it can also be modified to provide adjustable output for doing so the user have to use only two external resistors.
The IC dissipate heat during operation because all the voltage different between input and output will be converted in to heat therefore a heatsink is must to use with the IC or the IC will continuously go in to the overheat shutdown mode.
Applications:
Voltage step down applications
24V power supplies
Battery Chargers
Motor Drivers
Solar applications
Microcontroller based applications
Replacement and Equivalent / Other Part Numbers:
L78S24CV, MC7824, other than that an LM317 adjustable regulator IC can also be used for fixed 24V.
24V DC Power Supply Using LM7824 IC:
The figure below shows a 24V power supply circuit using LM7824 IC.
How to Safely Long Run in a Circuit:
To get long term performance from LM7824 IC it is suggested to not drive load of more than 1.5A through this IC, use a suitable heatsink with the IC and always operate the IC in temperature above 0 degree centigrade and below +125 degree centigrade and storage temperature of the IC should be between -65 degree centigrade to +150 degree centigrade.
