LT1375CS8#TRPBF

Overview

The LT1375CS8#TRPBF is a monolithic buck mode switching regulator manufactured by Analog Devices Inc. It integrates a 1.5A switch, oscillator, control circuitry, and logic within a single die. The device operates at a fixed 500kHz switching frequency to minimize external component size. It accepts an input voltage range of 6V to 25V and provides a fixed 5V output with a maximum current capability of 1.25A. Packaged in an SOIC-8 surface-mount format, it supports shutdown functionality for power management.

Feature Summary

• Integrates a high-current 1.5A internal switch with complete oscillator and control logic
• Utilizes a 500kHz fixed switching frequency to reduce the physical footprint of external passive components
• Includes dedicated shutdown pin for active power management and standby control

Applications

• Point-of-load regulation for microprocessors and digital logic circuits
• Battery-powered systems requiring efficient step-down conversion from higher voltages
• Industrial control modules utilizing standard 5V logic levels

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier source is authorized to guarantee part authenticity and traceability for critical designs.

Selection Notes

Select this component when a compact solution is required for converting 6V to 25V inputs down to 5V. The integrated 1.5A switch handles loads up to 1.25A efficiently. Consider the 500kHz frequency trade-off between component size and electromagnetic interference compared to lower frequency alternatives.

Part Context

This part belongs to the LT1375 series of monolithic buck regulators. It shares the core architecture with variants like LT1375IN8-5 but differs in package type and temperature rating. The CS8 designation specifies the commercial grade operating temperature range and SOIC-8 surface-mount package configuration.

Replacement Considerations

LT1375CS8-5#PBF offers identical electrical performance in tube packaging instead of reel.
