Frequently Asked Questions
What is the output voltage and accuracy of the L7824ABV?
The L7824ABV provides a fixed 24V output voltage with ±2% regulation accuracy. This tight tolerance ensures consistent performance in precision analog circuits, relay driver bias rails, and industrial measurement systems where a stable 24V reference is required.
What is the maximum input voltage for the L7824ABV?
The L7824ABV accepts a maximum input voltage of 37V in normal operation and can tolerate up to 40V absolute maximum. The minimum input voltage is 27.3V to maintain regulation. This input range makes it compatible with a variety of unregulated DC supplies and automotive-adjacent power sources.
What package does the L7824ABV use and how is it mounted?
The L7824ABV comes in a 3-pin TO-220 through-hole package, a widely used form factor that supports easy PCB installation and external heatsinking. The package's exposed metal tab can be bolted directly to a heatsink, allowing the regulator to dissipate significant power in high-current applications up to 1A.
What is the dropout voltage of the L7824ABV?
The L7824ABV has a nominal dropout voltage of 2V, meaning the input must be at least 2V higher than the 24V output (minimum 27.3V input) to maintain regulation. This relatively low dropout for a linear regulator helps minimize wasted power in designs where the input and output voltages are closely spaced.
What are common applications for the L7824ABV?
The L7824ABV is used in industrial control panels, test equipment, analog signal conditioning boards, relay driver circuits, and power supplies requiring a fixed 24V regulated output. Its proven reliability and simple 3-pin interface also make it a popular choice for retrofitting or maintaining legacy electronic equipment across industrial and commercial environments.
