LM78M05CH

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

The LM78M05CH/NOPB is a fixed-output linear voltage regulator from the LM78M series, manufactured by Texas Instruments. It provides a stable 5 V output with a maximum current capacity of 500 mA. The device utilizes a TO-39-3 through-hole package and operates within an extended temperature range of -40°C to +125°C. Key electrical specifications include a typical power supply rejection ratio (PSRR) of 78 dB, a static current of 4 mA, and line/load regulation values of 100 mV.

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

• Provides a fixed positive 5 V output for reliable power supply applications
• Capable of delivering up to 500 mA of continuous load current
• Operates reliably across an extended industrial temperature range

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

• General-purpose electronic circuit power conditioning
• Embedded system voltage regulation
• Industrial control unit power supplies

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

Verify the complete part number including the /NOPB suffix when sourcing, as it indicates lead-free compliance. Confirm the TO-39-3 package type matches your PCB footprint requirements. Ensure the supplier documentation aligns with Texas Instruments manufacturing standards for this specific component variant.

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

Select this component when a moderate 500 mA current capability is required in a through-hole configuration. It is suitable for designs needing operation at temperatures up to 125°C. Consider thermal management strategies due to the linear regulation method and potential power dissipation under high input-output differentials.

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

This component belongs to the LM78M family of three-terminal positive regulators. It offers higher current handling than the LM78L series but lower current than the standard LM7800 series. The TO-39 metal can package provides robust mechanical stability and thermal performance compared to plastic surface-mount alternatives.

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

Direct pin-compatible substitutes include other LM78M05 variants from Texas Instruments or equivalent manufacturers offering 500 mA fixed 5 V regulation in a TO-39 package. Verify that replacement parts meet the same -40°C to +125°C operating temperature range and electrical specifications.
