LT1376IN8#PBF

Overview

The LT1376IN8#PBF is a fixed-output step-down switching regulator manufactured by Analog Devices. It operates with an input voltage range of 5 V to 25 V and provides a fixed 5 V output at up to 1.5 A. The device utilizes a 500 kHz switching frequency and features a shutdown pin for power management. It is housed in an 8-pin PDIP package and supports through-hole mounting. The component functions as a buck converter within the LT1376 series, designed for efficient DC-DC conversion.

Feature Summary

• Integrated high-current switch capable of delivering 1.5 A
• Fixed 5 V output configuration for simplified design
• Built-in shutdown control for power optimization

Applications

• Point-of-load regulation for digital circuits
• Battery-powered systems requiring efficient step-down conversion
• Industrial control power supplies

Procurement Notes

Verify the specific suffix '#PBF' confirms lead-free compliance and RoHS standards. Confirm the 'I' temperature grade matches operational requirements against commercial alternatives. Ensure the PDIP-8 package aligns with existing PCB footprints before procurement.

Selection Notes

Select this part when a fixed 5 V output is required from a 5 V to 25 V input source. It is suitable for applications needing 1.5 A current capacity without external feedback resistors. Consider the PDIP-8 package if through-hole assembly is mandated over surface mount options.

Part Context

This component belongs to the LT1376 family of switching regulators. It shares core topology with adjustable variants like the LT1376CN8#PBF but offers a fixed 5 V output. The IN8 designation indicates the industrial temperature range and PDIP-8 packaging format.

Replacement Considerations

LT1376CN8-5#PBF is a documented direct substitute offering identical electrical specifications and functionality.
