LT3970EDDB-3.3#TRPBF

Overview

The LT3970EDDB-3.3#TRPBF is a monolithic buck switching regulator from Analog Devices Inc., housed in a 10-lead DFN package. It delivers a fixed 3.3V output at up to 350mA with an input voltage range of 4.2V to 40V. The device features an adjustable switching frequency from 200kHz to 2.2MHz and consumes only 2.5µA of quiescent current. Operating temperatures range from -40°C to 125°C.

Feature Summary

Adjustable switching frequency for optimized efficiency across load conditions
Ultra-low quiescent current consumption for extended battery life
Wide input voltage tolerance suitable for diverse power sources

Applications

Battery-powered portable instrumentation
Industrial control systems
Automotive electronics

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging. Confirm the EDDB variant matches required thermal performance. Check manufacturer documentation for RoHS compliance status and lead-free specifications before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.3V rail is required with minimal static power draw. Ensure the application input voltage remains within the 4.2V to 40V window. Consider the 350mA limit against peak load demands and verify thermal dissipation capabilities within the DFN footprint.

Part Context

This part belongs to the LT3970 family of high-efficiency step-down converters. It shares core architecture with other variants like the LT3970IDDB, differing primarily in temperature grade and packaging configuration. The series targets applications demanding low noise and high reliability in compact spaces.
