L78M15ABV

Overview

The L78M15ABV is a three-terminal positive linear voltage regulator from the L78MxxA series, manufactured by STMicroelectronics. It provides a fixed output voltage of 15 V with a maximum output current of 0.5 A. The device operates within an extended temperature range of -40 °C to +125 °C and features ±2% output voltage tolerance. It supports a maximum DC input voltage of 35 V and utilizes a TO-220 package for through-hole mounting.

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 compensation reduces output short-circuit current as voltage across the pass transistor increases

Applications

Local on-card regulation to eliminate distribution problems associated with single-point regulation
Replacement for Zener diode and resistor combinations in low-noise applications
Use with external power pass elements to construct high-current voltage regulators

Procurement Notes

Verify the specific suffix 'AB' confirms the extended temperature range (-40°C to 125°C) and ±2% tolerance. Confirm the package type matches the required PCB footprint (TO-220). Check the manufacturer's official documentation for any recent product change notices or environmental compliance updates such as ECOPACK grades before finalizing procurement.

Selection Notes

Select this component when a fixed 15 V output is required with up to 500 mA capacity. Ensure the input voltage remains within the 35 V absolute maximum rating. Consider the thermal resistance characteristics of the TO-220 package; adequate heat sinking may be necessary to sustain full load current without triggering thermal shutdown.

Part Context

This part belongs to the L78MxxA family of precision 500 mA regulators. The 'M' designation indicates the 500 mA current class, distinguishing it from the standard L78xx series which typically supports higher currents. The 'AB' suffix specifies the extended temperature grade and tighter voltage tolerance compared to the AC variant.
