LT1375CS8-5#TRPBF

Overview

The LT1375CS8-5#TRPBF is a monolithic buck mode switching regulator from Analog Devices, featuring an integrated 1.5A power switch and a fixed 500kHz oscillation frequency. It operates with an input voltage range of 6V to 25V and delivers a regulated output current up to 1.25A at a fixed 5V output. Packaged in an 8-pin SOIC for surface mount applications, the device includes essential oscillator, control, and logic circuitry on-die. This high-frequency operation allows for significant reduction in external component size while maintaining efficient DC-to-DC conversion performance.

Feature Summary

• Integrates a 1.5A power switch with complete oscillator and control logic
• Fixed 500kHz switching frequency minimizes external passive component requirements
• Includes shutdown capability for enhanced power management flexibility

Applications

• Battery-powered portable equipment requiring efficient step-down regulation
• Industrial systems utilizing 5V logic levels derived from higher voltage rails
• Distributed power architectures needing compact DC-DC conversion stages

Procurement Notes

Verify that the specific suffix #TRPBF corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the manufacturer designation remains Analog Devices Inc. and that the part number matches the exact 8-pin SOIC configuration. Ensure compliance with RoHS standards as indicated in official documentation before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5V output is required from a 6V to 25V input source within a compact surface-mount footprint. The integrated 1.5A switch supports loads up to 1.25A, making it suitable for moderate current applications. 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 high-efficiency step-down switching regulators. It shares architectural similarities with other members like the LT1375IN8-5#PBF but differs in package type and mounting style. The CS8 variant specifically denotes the small outline integrated circuit package designed for surface mount technology applications.

Replacement Considerations

LT1375CS8-5#PBF serves as a direct pin-compatible alternative differing only in tube packaging rather than reel.
