LT1534IS-1#TRPBF

Overview

The LT1534IS-1#TRPBF is an ultralow noise 2A switching regulator manufactured by Analog Devices Inc. It operates in a boost topology with an adjustable output voltage and supports an input voltage range of 2.7 V to 23 V. The device delivers up to 2 A of output current through a single channel. Key electrical specifications include a quiescent current of 12 mA and an adjustable switching frequency ranging from 20 kHz to 250 kHz. It functions within a temperature range of -40°C to +125°C and is housed in a SOIC-16 package.

Feature Summary

• Ultralow noise performance for sensitive analog circuits
• Integrated shutdown control capability
• Adjustable switching frequency for optimization

Applications

• Portable instrumentation requiring low noise power
• Battery-powered systems needing efficient voltage boosting
• Communication equipment power supplies

Procurement Notes

Verify the exact suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the SOIC-16 package matches your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high current delivery with minimal noise interference. Compare against the LT1534CS-1#PBF variant if tube packaging is preferred over reels. Consider the operating temperature range limits when designing for extreme environmental conditions.

Part Context

This part belongs to the LT1534 series of ultralow noise switching regulators. It shares architectural similarities with the LT1533 but offers higher current capacity. The IS-1 designation specifies the industrial temperature grade and specific pinout configuration within the Analog Devices portfolio.

Replacement Considerations

LT1534CS-1#PBF is a documented alternative offering identical electrical characteristics in tube packaging instead of tape and reel.
