L78M24CDT-TR

Overview

The L78M24CDT-TR is a fixed positive linear voltage regulator from the STMicroelectronics L78Mxx series, designed for surface-mount applications. It provides a fixed output voltage of 24 V with a maximum output current capability of 500 mA. The device operates within an input voltage range up to a maximum of 40 V and supports junction temperatures up to +150 °C. Key electrical parameters include a typical power supply rejection ratio (PSRR) of 50 dB at 120 Hz, a static current of 6 mA, line regulation of 100 mV, and load regulation of 480 mV. It is housed in a TO-252 package.

Feature Summary

Integrated protection mechanisms including overcurrent limiting, thermal shutdown, and safe area protection to ensure operational reliability under fault conditions.
Fixed internal reference architecture delivers stable regulated output without requiring external feedback components or complex biasing networks.
Designed for direct surface-mount integration into printed circuit boards using standard TO-252 footprint compatibility.

Applications

General-purpose power supply sections requiring stable 24 V rails
Battery-powered systems utilizing linear regulation stages
Industrial control equipment power distribution modules

Procurement Notes

Verify the specific suffix 'CDT' against the manufacturer's official datasheet to confirm the exact temperature grade and packaging configuration. Ensure that the ordering documentation explicitly references the L78M24CDT-TR part number to distinguish it from other variants within the L78Mxx family. Cross-reference component markings with official identification guides to prevent counterfeit substitution during assembly.

Selection Notes

Select this component when a fixed 24 V output is required with moderate current demands up to 500 mA. Consider the thermal dissipation requirements inherent to linear regulators operating with significant input-to-output voltage differentials. Evaluate the TO-252 package constraints regarding PCB copper area availability for adequate heat spreading compared to through-hole alternatives.

Part Context

This component belongs to the L78Mxx series of three-terminal positive linear regulators manufactured by STMicroelectronics. The series is characterized by robust construction and widespread industrial adoption for simple voltage regulation tasks. The 'M' designation indicates the medium-current variant within the broader L78 product line, offering a balance between performance and thermal management simplicity.
