LT1507CS8#PBF

Overview

The LT1507CS8#PBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates in a mono buck mode with a fixed switching frequency of 500 kHz. The device accepts an input voltage range from 4 V to 16 V and provides an adjustable output voltage between 2.42 V and 14.88 V. It delivers a maximum output current of 1.5 A through a single positive output channel. The component features a shutdown function and utilizes surface-mount technology in an 8-SOIC package.

Feature Summary

Integrates a complete step-down switching regulator circuit on a single monolithic chip
Provides adjustable output voltage capability within specified limits
Includes a dedicated shutdown pin for power management control

Applications

Battery-powered portable equipment requiring efficient voltage regulation
Offline DC/DC converter circuits
Post-regulator stages for modules exceeding standard bus voltages

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards. Confirm the SOIC-8 package dimensions match the target PCB footprint. Check manufacturer documentation for moisture sensitivity level and reflow soldering temperature profiles to ensure assembly compatibility.

Selection Notes

Select this component when a compact, high-efficiency buck solution is required for moderate current loads up to 1.5 A. Consider the 500 kHz switching frequency for balancing component size and efficiency. Ensure the input voltage range aligns with the available power source and that thermal dissipation capabilities of the SOIC package are sufficient for the application.

Part Context

This part belongs to the LT1507 series of switching regulators designed for cost-sensitive applications. It serves as a direct replacement for older linear regulators in systems where efficiency and thermal performance are critical. The device is categorized under PMIC - Power Management ICs, specifically Switching Voltage Regulators.
