LT1507CS8-3.3#PBF

Overview

The LT1507CS8-3.3#PBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc., housed in an 8-SOIC package. It operates with an input voltage range of 4V to 16V and provides a fixed output voltage of 3.3V at up to 1.5A output current. The device features a 500kHz switching frequency, 4mA static current, and includes shutdown functionality. It supports operation within a temperature range of 0°C to +70°C.

Feature Summary

Monolithic buck topology for efficient step-down conversion
Integrated shutdown control for power management
Fixed 3.3V output configuration

Applications

Battery-powered portable electronics
General-purpose DC-DC power supplies
Embedded system voltage regulation

Procurement Notes

Verify the specific suffix against official documentation to confirm the fixed 3.3V output variant. Ensure the SOIC-8 package matches design constraints. Confirm RoHS compliance status through manufacturer declarations prior to integration into production systems.

Selection Notes

Select this component when a fixed 3.3V output is required from a 4V to 16V input source. Consider the 1.5A current limit and 500kHz frequency for thermal and layout planning. Verify that the surface-mount SOIC-8 package fits the PCB footprint requirements.

Part Context

This part belongs to the LT1507 series of monolithic step-down switching regulators. It shares core architecture with other variants in the family but differs in output configuration and package type. The series is designed for applications requiring moderate current levels with high efficiency.
