Overview
The L78M05CDT-1 is a three-terminal positive linear voltage regulator from the L78Mxx series, manufactured by STMicroelectronics. It provides a fixed 5 V output with a maximum continuous current of 0.5 A. The device operates within an input voltage range of 7 V to 35 V and supports junction temperatures up to 150 °C. Packaged in the IPAK surface-mount format, it features internal thermal overload and short-circuit protection. The component exhibits a typical power supply rejection ratio of 62 dB and maintains an output voltage tolerance of 4% for the C version.
Feature Summary
- Provides local on-card regulation to eliminate distribution problems
- Includes thermal overload, short circuit, and output transition SOA protection
- Available in multiple surface-mount packages including IPAK
Applications
- Local on-card regulation
- General-purpose positive voltage regulation
- Battery chargers
Procurement Notes
Verify the specific suffix 'DT-1' against the manufacturer's official datasheet to confirm the IPAK package type and RoHS compliance status. Ensure the ordering code matches the required tape-and-reel packaging configuration. Cross-reference the part number with the latest ECAD models to guarantee footprint compatibility during procurement.
Selection Notes
Select this component when a fixed 5 V output at 0.5 A is required in a surface-mount design. The IPAK package offers a compact alternative to through-hole options while maintaining similar thermal characteristics. Consider the 4% output voltage tolerance and 62 dB PSRR for applications requiring moderate precision without external trimming.
Part Context
This part belongs to the L78Mxx series of three-terminal positive regulators, which are available in TO-220, TO-220FP, DPAK, and IPAK packages. The series is designed for wide-range applications with fixed output voltages including 5, 6, 8, 9, 10, 12, 15, and 24 V. The L78M05CDT-1 specifically utilizes the IPAK surface-mount form factor.
Replacement Considerations
Compatible substitutes include other L78M05 variants such as L78M05CV or L78M05CDT, provided the package style (TO-220 vs. IPAK) and mounting requirements are accommodated. Verify pinout compatibility and thermal performance differences between package types before substitution.
