What are the key features of L78L24CD-TR?
- Fixed 24V regulated output with tight 0.35% maximum line regulation for stable voltage-sensitive applications
- Wide input voltage range up to 38V (40V absolute max) enabling use directly from unregulated 24V-36V supplies
- SOIC-8 surface-mount package on tape and reel (TR suffix) for high-volume automated PCB assembly
- Internal current limiting and thermal shutdown protection for robust fault-tolerant operation
What is L78L24CD-TR used for?
The L78L24CD-TR is well-suited for providing a stable 24V reference or supply rail in industrial automation equipment, PLC backplanes, and sensor signal conditioning circuits. It is commonly used as a local post-regulator on industrial 24V bus systems where a clean, regulated voltage is needed for precision analog or measurement circuits. The compact SOIC-8 package and tape-and-reel format make it ideal for high-volume consumer appliances and building automation modules.

Frequently Asked Questions
What is the output voltage and maximum output current of the L78L24CD-TR?
The L78L24CD-TR provides a fixed 24V regulated output voltage with a maximum output current of 100mA. This makes it suitable for powering low-current circuits such as op-amps, analog sensors, and reference circuits that require a stable 24V supply.
What is the input voltage range for the L78L24CD-TR?
The L78L24CD-TR accepts input voltages from 27V minimum to 38V maximum, with a 40V absolute maximum rating. This range is designed to work with standard industrial 24V unregulated supplies that can vary significantly under load.
What package does the L78L24CD-TR use and what does the TR suffix indicate?
The L78L24CD-TR uses an SOIC-8 (R-PDSO-G8) surface-mount package. The 'TR' suffix indicates tape-and-reel packaging with 2500 units per reel, which is optimized for automated pick-and-place assembly in production environments.
What is the dropout voltage of the L78L24CD-TR?
The L78L24CD-TR has a nominal dropout voltage of 1.7V. This means the input voltage must be at least 25.7V to maintain a regulated 24V output, which is consistent with operation from industrial 27V-38V bus supplies.
Does the L78L24CD-TR have built-in protection features?
Yes, the L78L24CD-TR includes internal thermal overload protection and short-circuit current limiting. These built-in features protect both the regulator and the load circuit from damage during fault conditions, reducing the need for external protection components.
