LT1507IS8#PBF

Overview

The LT1507IS8#PBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates in a buck topology with an adjustable output voltage range from 2.42V to 14.88V. The device supports a maximum output current of 1.5A and functions within an input voltage window of 4V to 16V. It features a fixed switching frequency of 500kHz and includes shutdown functionality. The component is housed in an 8-SOIC package and is rated for operation between -40°C and +85°C.

Feature Summary

Integrates a high-side NPN power switch and low-side PNP synchronous rectifier for efficient step-down conversion
Provides internal compensation to minimize external component count
Includes thermal shutdown protection to safeguard the device during overload conditions

Applications

Battery-powered portable equipment requiring regulated supply rails
Post-regulation of higher voltage bus lines in industrial systems
Embedded controller logic power supplies

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and temperature grade. Ensure the ordering part number matches the required package style and RoHS compliance status. Cross-reference the manufacturer's latest datasheet to validate availability and any potential design changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a compact, single-output synchronous buck solution is required for moderate current loads up to 1.5A. It is suitable for designs prioritizing efficiency over ultra-low quiescent current. Consider the 500kHz switching frequency for balancing component size and electromagnetic interference. Verify that the input voltage range aligns with the system's power source constraints.

Part Context

This part belongs to the LT1507 series of monolithic step-down switching regulators. The series is characterized by its integrated synchronous rectification and robust performance in space-constrained applications. The IS8 designation indicates the industrial temperature range and SOIC-8 package variant within the broader product family.
