LT3970EMS-5#TRPBF

Overview

The LT3970EMS-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 provides a fixed output voltage of 5V at a maximum current of 350mA. The device features an adjustable switching frequency from 200kHz to 2.2MHz and consumes only 1.8µA of quiescent current. It is housed in a 10-lead MSOP package and supports operation temperatures from -40°C to +125°C.

Feature Summary

Integrates high-voltage MOSFETs for efficient step-down conversion
Features ultra-low quiescent current for extended battery life
Supports adjustable switching frequencies up to 2.2MHz

Applications

Battery-powered portable equipment
Industrial control systems
Automotive electronics

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the EMS designation corresponds to the MSOP-10 package variant. Ensure compatibility with required thermal management solutions for the specified operating temperature range.

Selection Notes

Select this component for applications requiring wide input voltage tolerance and low standby power consumption. The fixed 5V output simplifies design compared to adjustable variants. Consider the MSOP-10 package constraints for PCB layout and thermal dissipation requirements.

Part Context

This part belongs to the LT3970 family of micropower synchronous buck regulators. It shares core architecture with other LT3970 variants but differs in output voltage configuration and package type. The series is designed for space-constrained, battery-operated applications requiring high efficiency.
