LT1576IS8-5#TRPBF

Overview

The LT1576IS8-5#TRPBF is a step-down switching regulator manufactured by Analog Devices, operating at a fixed 200 kHz frequency. It provides a regulated 5 V output with a maximum current capacity of 1.5 A. The device accepts an input voltage range from 5 V to 25 V and features a shutdown function for power management. It operates within a temperature range of -40°C to +125°C and utilizes an 8-pin SOIC package.

Feature Summary

Integrates a high-efficiency buck converter topology for DC-DC step-down conversion
Includes a dedicated shutdown pin to minimize quiescent current during standby modes
Provides stable regulation with integrated compensation for transient response

Applications

Point-of-load regulation in industrial control systems
Power supply stages for embedded computing modules
Battery-powered equipment requiring efficient voltage stepping

Procurement Notes

Verify the suffix #TRPBF indicates tape-and-reel packaging distinct from tube variants. Confirm the manufacturer designation as Analog Devices Inc., formerly Linear Technology. Ensure RoHS compliance documentation matches the specific production lot. Validate that the SOIC-8 footprint aligns with PCB design requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5 V output is required from a 5 V to 25 V input source. The 1.5 A output capability suits moderate load applications. The 200 kHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify thermal performance under maximum load conditions given the SOIC-8 package constraints.

Part Context

This part belongs to the LT1576 series of switching regulators designed for general-purpose power management. It serves as a drop-in replacement for older linear regulators in efficiency-critical designs. The IS8-5 variant specifically denotes the industrial temperature range and fixed 5 V output configuration within the broader family.
