LT3970IMS-5#TRPBF

Overview

The LT3970IMS-5#TRPBF is a micropower step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 4.2V to 40V and provides a fixed output voltage of 5V at up to 350mA. The device features adjustable switching frequencies from 200kHz to 2.2MHz and ultra-low quiescent current consumption of 1.8µA. It utilizes a 10-lead MSOP package and supports operation temperatures from -40°C to +125°C.

Feature Summary

Integrates high-side and low-side power switches for efficient buck conversion without external diodes
Supports adjustable switching frequency selection to optimize efficiency or minimize external component size
Features cycle-by-cycle current limit and thermal shutdown protection for robust operation

Applications

Battery-powered portable equipment requiring extended runtime
Industrial control systems with wide input voltage ranges
Automotive electronics operating within specified temperature limits

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm availability status as supply constraints may affect immediate procurement. Ensure compatibility with surface-mount assembly processes for the MSOP-10 package format.

Selection Notes

Select this part for applications requiring a fixed 5V output from a wide input range. Consider the adjustable frequency feature if electromagnetic interference filtering needs optimization. Verify that the 350mA output current meets load requirements while maintaining thermal performance in the MSOP enclosure.

Part Context

This component belongs to the LT3970 family of micropower buck regulators designed for space-constrained, battery-operated devices. It shares core architecture with variants offering different output voltages or packages, such as the IMS and IDDB series, providing design flexibility across Analog Devices' power management portfolio.
