L78M24ABDT-TR

Overview

The L78M24ABDT-TR is a three-terminal positive linear voltage regulator from the L78MxxA series, manufactured by STMicroelectronics. It provides a fixed output voltage of 24 V with an output current capability up to 0.5 A. The device operates within an extended temperature range of -40 °C to +125 °C and features ±2% output voltage tolerance. Maximum ratings include a DC input voltage of 40 V for this specific output voltage. It is housed in a surface-mount DPAK (TO-252) package.

Feature Summary

Integrated thermal overload protection that shuts down the circuit during excessive power conditions
Internal short-circuit protection limits maximum output current
Output transistor safe-area protection reduces output short-circuit current as voltage across the pass transistor increases

Applications

Local on-card regulation
Distribution systems requiring elimination of single-point regulation issues
Adjustable voltage and current circuits using external components

Procurement Notes

Verify the component matches the exact part number L78M24ABDT-TR, specifically confirming the 'AB' suffix which denotes the extended temperature range (-40°C to 125°C). Ensure the package type corresponds to DPAK/TO-252. Confirm RoHS compliance status if required by your assembly specifications.

Selection Notes

Select this regulator when a fixed 24 V output is required with currents up to 0.5 A in space-constrained applications utilizing surface-mount technology. The AB variant is suitable for environments requiring operation below 0 °C. Ensure adequate heat sinking is provided to maintain performance at full load current.

Part Context

This component belongs to the L78MxxA family of precision 500 mA regulators available in multiple fixed output voltages. The series is designed for applications where local regulation is preferred over centralized distribution. The DPAK package offers a compact solution compared to through-hole alternatives like TO-220.
