BD3501FVM-TR

Overview

The BD3501FVM-TR is an N-channel FET ultra-low dropout (LDO) linear regulator controller designed for PC chipset applications. It operates within a supply voltage range of 4.5 V to 7 V and provides a fixed output voltage of approximately 1.2 V with a maximum output current capability of 4 A. The device utilizes an MSOP-8 package and supports surface-mount installation. It functions as a driver IC for external pass transistors, offering precise regulation for low-voltage digital logic.

Feature Summary

• Designed specifically for powering PC chipsets requiring stable low-voltage rails
• Integrates control circuitry for external N-channel MOSFET pass elements
• Supports high output current delivery through external transistor configuration

Applications

• Power supply circuits for PC chipsets
• Low-voltage core voltage generation for digital logic
• System-on-chip power management architectures

Procurement Notes

Verify the specific suffix and tape-and-reel quantity against the manufacturer's latest datasheet before ordering. Confirm that the component status remains active or suitable for your design lifecycle requirements. Ensure compatibility with existing PCB footprints and thermal management strategies for the MSOP-8 package.

Selection Notes

Select this component when designing power stages for PC chipsets that require high current capacity beyond integrated LDO limits. It is appropriate for systems needing a fixed 1.2 V rail derived from a 5 V input. Consider the need for external N-channel MOSFETs and associated passive components for stability and thermal performance.

Part Context

This part belongs to ROHM's family of ultra-low dropout linear regulator controllers tailored for computer motherboard and chipset power distribution. These controllers manage external pass devices to achieve higher efficiency and current handling than monolithic LDOs, addressing the specific voltage and current demands of modern computing processors.
