L78M05ABDT-TR

Overview

The L78M05ABDT-TR is a three-terminal positive linear voltage regulator from the L78MxxA series, manufactured by STMicroelectronics. It provides a fixed output voltage of 5 V with a maximum output current capability of 0.5 A. The device features an extended operating junction temperature range from -40 °C to +125 °C and offers a tight output voltage tolerance of ±2 %. It is housed in a DPAK (TO-252) surface-mount package.

Feature Summary

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

Applications

Local on-card regulation for electronic circuits
Eliminating distribution problems associated with single-point regulation
General-purpose fixed voltage power supply applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the reel quantity and tape specifications. Ensure the component grade matches the required environmental compliance standards for your application. Cross-reference the datasheet revision history to validate the electrical characteristics and mechanical dimensions provided.

Selection Notes

Select this component when a fixed 5 V output is required with a maximum load current of 0.5 A. The extended temperature range makes it suitable for industrial environments. Verify that the input voltage remains within the absolute maximum ratings and that adequate heat sinking is provided if the power dissipation exceeds the thermal resistance limits of the DPAK package.

Part Context

This part belongs to the L78MxxA family of precision regulators, which are designed to provide local on-card regulation. The series includes various fixed output voltages and is available in TO-220 and DPAK packages. These devices are intended to replace discrete regulation solutions by offering integrated protection features in a compact form factor.
