LT1507CS8#TRPBF

Overview

The LT1507CS8#TRPBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates in a fixed buck topology with an adjustable output voltage range from 2.42V to 14.88V. The device delivers a maximum output current of 1.5A and functions within an input voltage window of 4V to 16V. It integrates a 500kHz switching frequency and supports shutdown functionality. The component is housed in an 8-SOIC surface-mount package and is rated for operation between 0°C and +70°C.

Feature Summary

Integrates a high-efficiency power switch and control circuitry for compact step-down conversion
Features a fixed 500kHz switching frequency to minimize external passive component size
Includes a dedicated shutdown pin for low-power standby management

Applications

Battery-powered portable equipment requiring efficient voltage regulation
Post-regulation stages for higher voltage DC bus systems
General-purpose 5V or 3.3V distribution networks

Procurement Notes

Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity. Confirm that the commercial temperature grade aligns with system requirements, as industrial variants may carry different suffixes. Validate RoHS compliance details directly from the latest datasheet revision.

Selection Notes

Select this component when a fixed-frequency buck converter is required for moderate current loads up to 1.5A. Ensure the input voltage remains within the 4V to 16V operational range. Consider the 8-SOIC package constraints for thermal management and PCB layout. Verify that the adjustable output voltage setting meets the specific load requirements using external resistors.

Part Context

This part belongs to the LT1507 series of monolithic step-down switching regulators. It shares functional similarities with other members like the LT1507IS8 but differs in temperature rating and packaging options. The series is designed for applications needing simple, cost-effective DC-DC conversion without complex synchronization requirements.
