LT1376CN8#PBF

Overview

The LT1376CN8#PBF is a step-down switching regulator manufactured by Analog Devices, housed in an 8-pin PDIP package. It operates with an input voltage range of 5 V to 25 V and delivers up to 1.5 A output current. The device features a fixed 500 kHz switching frequency and supports adjustable output voltages. It includes shutdown functionality and maintains a low quiescent current of 20 uA. The component functions within a temperature range of 0°C to +125°C.

Feature Summary

• Integrates a power switch for efficient buck conversion
• Supports adjustable output voltage configuration
• Includes shutdown control for power management

Applications

• Point-of-load regulation
• Battery-powered systems
• General-purpose DC-DC conversion

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and electrical characteristics. Ensure the PDIP-8 through-hole package matches the target PCB layout requirements. Confirm RoHS compliance status via the manufacturer's declaration before integration into regulated assemblies.

Selection Notes

Select this component when a through-hole solution is required for high-current buck applications. The 1.5 A capability suits moderate load designs. Verify that the 5 V minimum input constraint aligns with the source supply. Consider thermal dissipation limits inherent to the PDIP package for high ambient temperatures.

Part Context

This part belongs to the LT1376 series of switching regulators. It shares functional similarities with surface-mount variants like the LT1376IS8 but utilizes a dual inline package for easier prototyping or legacy board designs. The series is characterized by high efficiency and robust performance under varying load conditions.

Replacement Considerations

LT1376CN8-5#PBF provides a fixed 5 V output instead of adjustable.
