LT1576IS8#TRPBF

Overview

The LT1576IS8#TRPBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5 V to 25 V and provides a fixed 5 V output at up to 1.5 A. The device integrates a 200 kHz switching frequency, offering high efficiency in a compact SOIC-8 surface-mount package. It features a shutdown mode with low quiescent current of 1.16 mA during operation.

Feature Summary

• Integrates a power switch for efficient step-down conversion
• Includes internal frequency compensation for stable operation
• Features thermal shutdown protection for reliability

Applications

• Point-of-load regulation for embedded systems
• Battery-powered equipment requiring efficient voltage stepping
• General-purpose 5V distribution networks

Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. to ensure component authenticity. Check RoHS compliance status via official documentation before integration into regulated assemblies.

Selection Notes

Select this part for applications requiring a fixed 5V output from higher input rails up to 25V. The 1.5A current capability suits moderate load requirements. Consider the SOIC-8 package for space-constrained designs where through-hole options are unsuitable.

Part Context

This component belongs to the LT1576 series of high-efficiency buck regulators. It is designed as a drop-in replacement for older linear regulators in 5V systems, offering significantly improved thermal performance and efficiency under heavy load conditions compared to traditional LDOs.
