RC1584MT

Overview

The RC1584MT is an adjustable positive Low Dropout (LDO) regulator manufactured by Fairchild Semiconductor. It operates within a minimum output voltage of 1.5V and a maximum of 3.6V, featuring a typical dropout voltage of 1.3V. The device utilizes bipolar technology and is housed in a TO-263 package with three pins. This component is designed for applications requiring stable voltage regulation with minimal voltage drop across the regulator.

Feature Summary

• Adjustable positive output voltage capability
• Low dropout voltage operation for efficiency
• Bipolar technology construction

Applications

• General purpose voltage regulation
• Battery-powered systems requiring low dropout
• Embedded power supply circuits

Procurement Notes

Verify the exact manufacturer and date code upon procurement. Confirm that the received component matches the specified TO-263 plastic package and three-pin configuration. Ensure compatibility with your circuit's thermal requirements and input voltage range before integration.

Selection Notes

Select this component when an adjustable positive output between 1.5V and 3.6V is required. Consider its 1.3V dropout characteristic for applications where input voltage is close to the desired output. Verify that the TO-263 package suits your board space and thermal dissipation needs compared to other available LDO options.

Part Context

This part belongs to the RC1584 series of LDO regulators from Fairchild Semiconductor. Related variants include fixed-output versions like the RC1584M15, which provides a fixed 1.5V output. The MT suffix typically denotes the specific tape-and-reel packaging or variant within the TO-263 form factor, distinguishing it from other package styles in the same family.

Replacement Considerations

Direct substitutes may include other adjustable LDOs with similar voltage ranges and dropout characteristics. Check for equivalent packages such as TO-263. Fixed-output alternatives like the RC1584M15 are only suitable if a constant 1.5V output is acceptable.
