KA78M08RTM

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

The KA78M08RTM is a three-terminal positive linear voltage regulator manufactured by Fairchild Semiconductor. It provides a fixed output voltage of 8 V with a maximum output current capability of 500 mA. The device is housed in a D-PAK (TO-252) surface-mount package. It supports an input voltage range up to 35 V and operates within a temperature range of 0°C to +125°C. Internal protections include thermal shutdown and safe operating area limitations.

• Battery-powered systems needing efficient voltage regulation
• General-purpose power supplies in consumer electronics

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

Verify the manufacturer status as Fairchild Semiconductor was acquired by ON Semiconductor. Confirm if the specific KA78M08RTM part number is still actively produced or classified as obsolete. Check datasheet revisions to ensure electrical specifications match current design requirements before procurement.

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

Select this component when a fixed 8 V output at 500 mA is required in a surface-mount form factor. Ensure the input voltage does not exceed the maximum rating of 35 V. Consider thermal management needs due to the TO-252 package size and potential power dissipation under load conditions.

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

This component belongs to the KA78M series of three-terminal positive regulators, which are industry-standard replacements for the LM78xx family. The 'M' suffix indicates a 500 mA current rating, distinguishing it from the standard 1A variants. The RTM suffix typically denotes the D-PAK package and reel/cut-tape shipping configuration.

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

Equivalent parts include MC78M08CDTXM and LM78M08. Verify pinout compatibility and thermal characteristics when substituting. Note that some equivalents may have different package dimensions or slight variations in dropout voltage.
