LT3970HMS-5#TRPBF

Overview

The LT3970HMS-5#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 4.2V to 40V and delivers a fixed output voltage of 5V at up to 350mA. The device features an adjustable switching frequency from 200kHz to 2.2MHz and consumes only 1.8µA of quiescent current. Packaged in a 10-lead MSOP, it supports operation temperatures from -40°C to +150°C.

Feature Summary

Adjustable switching frequency allows optimization for efficiency or component size
Ultra-low quiescent current enables extended battery life in portable applications
Wide input voltage range accommodates various power supply sources

Applications

Battery-powered portable equipment
Industrial control systems
Automotive electronics
Communication infrastructure

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure correct voltage regulation and package type. Check official distributor channels for availability as supply may be limited. Ensure compatibility with required operating temperature ranges for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a fixed 5V output is required from a wide input voltage range. The adjustable frequency feature allows designers to optimize external component sizes. Consider the MSOP package constraints for thermal management. Verify that the 350mA output current meets the load requirements of the target circuit design.

Part Context

This part belongs to the LT3970 family of high-efficiency step-down converters. The family is characterized by low quiescent current and wide input voltage capabilities. The HMS-5 variant specifically provides a fixed 5V output, distinguishing it from adjustable versions within the same series.
