LT1374IS8-5#TRPBF

Overview

The LT1374IS8-5#TRPBF is a monolithic buck switching regulator from Analog Devices, housed in an SOIC-8 surface-mount package. It operates with a fixed 5 V output and delivers up to 3.6 A of continuous output current. The device accepts an input voltage range from 5 V to 25 V and switches at a frequency of 500 kHz. Quiescent current is specified at 20 uA, while operating supply current is 2.5 mA. It supports a shutdown function and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates high-current buck switching regulation in a compact SOIC-8 package
• Features low quiescent current for improved efficiency during standby or light load conditions
• Includes a dedicated shutdown pin for power management control

Applications

• Point-of-load regulation for digital logic circuits
• Powering microcontrollers and DSPs from higher bus voltages
• Battery-powered systems requiring efficient step-down conversion

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the IS grade meets the required industrial temperature range specifications for your application environment. Ensure compatibility with the SOIC-8 footprint on your PCB layout.

Selection Notes

Select this part when a fixed 5 V output is required from inputs between 5 V and 25 V. The IS grade is suitable for industrial environments requiring operation down to -40°C. Consider the SOIC-8 thermal performance for your expected load currents.

Part Context

This component belongs to the LT1374 series of high-efficiency, high-current step-down switching regulators. The series offers various output voltage options and package configurations, including adjustable versions and different thermal packages like DPAK.

Replacement Considerations

LT1374CS8-5#PBF is a parameter-equivalent alternative in tube packaging. LT1374IS8-5#PBF is the same electrical specification but in tube form rather than tape-and-reel.
