LT1575CS8#TRPBF

Overview

The LT1575CS8#TRPBF is a low-dropout linear regulator manufactured by Analog Devices, formerly Linear Technology. It provides a fixed positive output voltage of 5 V with a maximum load current capability of 10 A. The device operates within an input voltage range of 5 V to 22 V and features fast transient response characteristics. It is housed in an 8-pin SOIC surface-mount package and is designed for applications requiring high efficiency and stability under heavy load conditions.

Feature Summary

• Delivers high output current up to 10 A with low dropout voltage operation
• Provides fast transient response to maintain regulation during rapid load changes
• Features fixed output voltage configuration for simplified circuit design

Applications

• High-current digital logic power supplies
• Post-regulation for switching power converters
• Power distribution networks requiring stable 5 V rails

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the manufacturer designation aligns with Analog Devices Inc., as Linear Technology was acquired. Ensure the part number matches the fixed 5 V output variant to avoid confusion with adjustable or other voltage versions in the LT1575 series.

Selection Notes

Select this component when a fixed 5 V output at 10 A is required with minimal external components. Consider the thermal performance of the SOIC-8 package for heat dissipation requirements. Verify input voltage constraints do not exceed the 22 V maximum rating. Compare against other LDOs if lower quiescent current or higher PSRR is needed for noise-sensitive applications.

Part Context

This part belongs to the LT1575 family of low-dropout regulators known for high current capability and fast transient response. The CS8 suffix denotes the commercial temperature range and SOIC-8 package style. The #TRPBF suffix specifies the reel packaging format and lead-free compliance status for automated assembly processes.

Replacement Considerations

LT1575CS8-5#PBF: Same electrical specifications but in tube packaging instead of tape-and-reel.
