LT1534IS#PBF

Overview

The LT1534IS#PBF is an ultralow noise 2A switching regulator manufactured by Analog Devices Inc. (formerly Linear Technology). It operates as a boost converter with an adjustable output voltage and supports a wide input voltage range from 2.7 V to 23 V. The device delivers up to 2 A of output current through a single output channel. It features a switch frequency range of 20 kHz to 250 kHz and maintains a typical quiescent current of 12 mA. The component is housed in a 16-pin SOIC package and is rated for operation between -40°C and +125°C.

Feature Summary

Provides ultralow noise performance suitable for sensitive analog circuits
Integrates a high-efficiency 2A power switch for robust current delivery
Supports wide input voltage ranges for flexible power supply designs
Includes shutdown functionality to minimize standby power consumption

Applications

Portable battery-powered equipment requiring low-noise power rails
RF and communication systems needing clean DC power supplies
Industrial control systems operating within wide temperature ranges
Automotive electronics utilizing boost topologies for voltage regulation

Procurement Notes

Verify the manufacturer part number LT1534IS#PBF against official Analog Devices documentation to ensure authenticity. Confirm that the suffix #PBF indicates lead-free RoHS compliance. Check the specific datasheet revision for any updates regarding thermal characteristics or pinout configurations before finalizing procurement orders.

Selection Notes

Select this component when designing boost converters that require high output current alongside minimal output noise. Ensure the application demands an input voltage compatible with the 2.7 V to 23 V range. Consider the SOIC-16 package constraints for PCB layout and verify that the required switching frequency falls within the specified 20 kHz to 250 kHz operational window.

Part Context

This part belongs to the LT1534 series of ultralow noise switching regulators. It is designed to replace older linear regulators in applications where efficiency and noise are critical. The IS variant denotes the industrial temperature grade, ensuring reliable performance across a broader environmental spectrum compared to commercial grades.
