MC78M05CDT-TP

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MC78M05CDT-TP is a three-terminal positive voltage regulator manufactured by Micro Commercial Components. It belongs to the MC78M05CDT series and functions as a linear voltage regulator within the PMIC category. The device provides a fixed output voltage of 5V with an output current capability exceeding 0.5 Amperes. It is housed in a surface-mount package, specifically identified as DPAK or TO-252, suitable for automated assembly via reel or cut tape packaging formats.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Internal thermal overload protection safeguards against excessive heat generation during operation.
• Integrated short-circuit current limiting protects the component from damage during fault conditions.
• High power dissipation capability allows for effective thermal management in compact designs.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

• General-purpose power supply regulation
• Local on-card regulation for digital logic circuits
• Battery charging systems requiring stable input voltages

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix (TP vs BP) to confirm packaging type and compliance status. Confirm RoHS certification details through official MCC documentation. Check current lifecycle status as availability may vary. Ensure the selected package matches the PCB footprint requirements. Validate that the manufacturer source is authorized to guarantee part authenticity.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 5V output with moderate current drive is required. Ensure the input voltage remains sufficiently above the dropout voltage for proper regulation. Verify that the thermal design accommodates the power dissipation based on the load current and ambient temperature. Confirm compatibility with the intended surface-mount assembly process.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part is part of the MC78MxxCDT family of three-terminal positive regulators. It shares functional similarities with other industry-standard 78M05 devices but is specific to Micro Commercial Components manufacturing. The CDTSuffix indicates the DPAK/TO-252 package style. It serves as a direct replacement for legacy through-hole regulators in modern surface-mount applications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct pin-compatible substitutes include L7805CDT from STMicroelectronics and LM78M05 variants from other manufacturers. Verify that alternative parts meet the same 0.5A output current requirement and thermal protection specifications. Ensure package dimensions match the existing PCB layout to avoid mechanical interference.
