LT1376IS8-5#TRPBF

Overview

The LT1376IS8-5#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 5 V to 25 V and provides a fixed 5 V output at up to 1.5 A. The device integrates a 500 kHz switching frequency, enabling efficient power conversion in compact designs. Key electrical specifications include a maximum supply current of 2.5 mA and a shutdown feature for power management. It supports operation across a temperature range of -40°C to +125°C and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Integrates a high-efficiency buck converter topology with a fixed 500 kHz switching frequency
• Includes a shutdown pin for active power management and reduced quiescent current consumption
• Features a robust internal switch capable of delivering up to 1.5 A of continuous output current

Applications

• Point-of-load regulation for embedded systems requiring stable 5 V rails
• Battery-powered equipment utilizing step-down conversion from higher voltage sources
• Industrial control modules operating within extended temperature environments

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging distinct from tube variants like #PBF. Confirm the IS8 designation corresponds to the SOIC-8 package and industrial temperature rating. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5 V output is required from inputs between 5 V and 25 V. It is suitable for applications prioritizing moderate switching frequencies to balance EMI and component size. Consider the 1.5 A current limit and SOIC-8 thermal dissipation capabilities relative to the expected load profile and ambient conditions.

Part Context

This part belongs to the LT1376 series of monolithic step-down switching regulators. It shares functional similarities with other members like the LT1376IN8-5#PBF but differs in packaging and reel configuration. The series is designed for general-purpose DC-DC conversion tasks requiring integrated power switches and simple external component counts.

Replacement Considerations

LT1376IS8-5#PBF is a direct substitute differing only in tube packaging instead of tape-and-reel.
