Overview
The L78M15CDT-TR is a fixed-output positive linear voltage regulator from the STMicroelectronics L78M series. It provides a nominal output voltage of 15 V with a maximum output current capability of 500 mA. The device operates within an input voltage range up to a maximum of 35 V and supports junction temperatures up to 150 °C. It utilizes a surface-mount TO-252 (DPAK) package with three terminals. Key electrical characteristics include a typical power supply rejection ratio of 54 dB at 120 Hz and a static current of 6 mA.
Feature Summary
- Integrated safety mechanisms including thermal overload protection, short-circuit protection, and safe operating area protection.
- Designed for local card regulation to eliminate issues associated with single-point stabilization.
- Fixed output configuration ensures stable voltage delivery without external feedback components.
Applications
- General-purpose linear voltage regulation in electronic circuits
- Local on-board voltage regulation for integrated circuits
- Power management sections requiring fixed positive voltage rails
Procurement Notes
Verify the specific manufacturer datasheet for the L78MxxC series to confirm exact electrical tolerances and thermal characteristics. Ensure the procurement specification matches the required output voltage and current ratings. Confirm package compatibility with the intended PCB footprint. Validate that the component meets all necessary environmental and compliance standards for the target application.
Selection Notes
Select this component when a fixed 15 V output is required with moderate current demands up to 500 mA. Consider the thermal dissipation requirements due to the linear regulation topology. Evaluate the input-to-output voltage differential to ensure operation within the specified dropout limits. Compare against other L78M variants if different voltage levels are needed while maintaining the same package and performance profile.
Part Context
This part belongs to the L78Mxx family of three-terminal positive linear regulators manufactured by STMicroelectronics. The L78M series offers 500 mA output current capability, distinguishing it from the higher-current L78 series and lower-current L78L series. These devices are widely used for their reliability and simplicity in providing regulated DC voltages from unregulated or varying DC sources.
Replacement Considerations
MC7815BDTRKG is a confirmed substitute part number available from onsemi. Verify pinout compatibility and electrical specifications before substitution.
