LT1579CGN-5#PBF

Battery Management Overview

The LT1579CGN-5#PBF is a low-dropout linear regulator manufactured by Analog Devices Inc., featuring dual inputs for smart battery backup applications. It provides a fixed 5 V output with a maximum current of 300 mA. The device operates within an input voltage range of 2.7 V to 20 V and maintains a typical power supply rejection ratio of 70 dB. Key electrical specifications include a dropout voltage of 400 mV, quiescent current of 50 uA, line regulation of 1.5 mV, and load regulation of 5 mV. It is housed in a 16-lead SSOP package and supports operation from 0°C to +125°C.

Battery Management Feature Summary

• Dual input architecture designed for intelligent battery backup systems
• Low quiescent current consumption suitable for energy-efficient designs
• High power supply rejection ratio for noise reduction

Battery Management Applications

• Smart battery backup regulators
• Portable electronic devices requiring stable 5 V rails
• Battery-powered systems with dual power sources

Battery Management Procurement Notes

Verify the specific suffix (CGN) corresponds to the SSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering part number matches the required temperature grade and packaging format to avoid integration errors during procurement.

Battery Management Selection Notes

Select this component for applications requiring a fixed 5 V output with 300 mA capability and dual-input functionality. Consider the SSOP-16 package constraints and thermal performance at higher ambient temperatures. Evaluate the 400 mV dropout voltage against minimum input supply conditions to ensure proper regulation under all load scenarios.

Battery Management Part Context

This part belongs to the LT1579 series of low-dropout regulators. It shares core electrical characteristics with variants like LT1579CS-5#PBF but differs in physical packaging. The CGN designation specifically indicates the 16-lead SSOP form factor, distinguishing it from SOIC or other package options within the same product family.

Battery Management Replacement Considerations

LT1579CS-5#PBF offers identical electrical performance in an SOIC-16 package. LT1579CGN-5#TRPBF provides the same SSOP-16 form factor in tape-and-reel packaging for automated assembly.
