RC1584T

Overview

The RC1584T is a single-output voltage regulator converter IC designed for Intel Pentium II GTL+ applications. It operates with an input voltage range of 3.5V to 7V and provides an adjustable output voltage between 1.5V and 3.6V. The device is housed in a TO-220-3 package and supports through-hole mounting. It functions within a junction temperature range of 0°C to 125°C.

Feature Summary

• Designed specifically as a converter for Intel Pentium II GTL+ systems
• Provides regulated single output voltage conversion
• Supports through-hole installation in TO-220-3 packages

Applications

• Intel Pentium II GTL+ power supply circuits
• Desktop computer motherboard voltage regulation
• Legacy processor core voltage conversion

Procurement Notes

Verify component status carefully, as this part may be discontinued. Confirm package integrity and pinout compatibility with existing board layouts before integration. Ensure sourcing channels provide authentic onsemi products to avoid counterfeit risks associated with legacy components.

Selection Notes

Select this component only when designing for or repairing systems requiring specific Intel Pentium II GTL+ voltage levels. Verify that the input supply falls within the 3.5V to 7V range. Consider thermal management requirements due to the TO-220-3 package's power dissipation characteristics in high-current scenarios.

Part Context

This regulator belongs to the RC1584 family from onsemi, specialized for legacy Intel processor power management. It addresses the specific voltage conversion needs of Pentium II platforms using GTL+ signaling standards. The device represents a dedicated solution for stable core voltage delivery in older desktop architectures.

Replacement Considerations

Check for direct substitutes like FAN1587 series variants if available, though pinouts and specifications must match exactly. Verify compatibility with GTL+ requirements before substituting.
