Overview
The L78M15ABV-DG is a three-terminal positive linear voltage regulator from the L78MxxA series by STMicroelectronics. It provides a fixed output voltage of 15 V with an output current capability up to 0.5 A. The device features ±2% output voltage tolerance and operates within an extended temperature range of -40 °C to +125 °C. It is housed in a TO-220 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 compensation reducing stress under high voltage differentials
Applications
- Local on-card regulation for electronic circuits
- Elimination of distribution problems associated with single-point regulation
- Replacement for Zener diode and resistor combinations
Procurement Notes
Verify the specific suffix 'DG' against official manufacturer documentation, as datasheets primarily reference 'L78M15AB'. Confirm RoHS compliance status and environmental specifications such as ECOPACK grade directly with the supplier or manufacturer before procurement.
Selection Notes
Select this component when a fixed 15 V output is required with moderate current demands up to 0.5 A. Ensure adequate heat sinking is provided to manage power dissipation, as performance relies on thermal management. Verify input voltage ranges accommodate the dropout voltage requirements for stable operation.
Part Context
This part belongs to the L78MxxA precision regulator family, designed for applications requiring local regulation. The series includes various fixed output voltages and is available in TO-220 and DPAK packages. These regulators are intended to eliminate noise and distribution issues found in single-point regulation systems.
Replacement Considerations
Compatible substitutes include other L78M15 variants from STMicroelectronics or equivalent three-terminal regulators from other manufacturers offering 15 V output and 0.5 A current capacity in a TO-220 package.
