LT1533IS#TRPBF

Overview

The LT1533IS#TRPBF is a micropower push-pull switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7 V to 23 V and delivers up to 1 A output current. The device features ultralow noise characteristics, making it suitable for sensitive analog circuits. It includes a shutdown function and supports adjustable switching frequencies between 20 kHz and 250 kHz. Packaged in a 16-lead SOIC, it functions within a temperature range of -40°C to +100°C.

Feature Summary

Ultralow noise performance designed for sensitive analog applications
Micropower operation with low quiescent current consumption
Integrated shutdown capability for power management
Push-pull topology supporting wide input voltage ranges

Applications

Portable instrumentation requiring low noise power supplies
Battery-powered systems needing efficient step-down regulation
Industrial control circuits with strict EMI constraints
Medical equipment requiring isolated or clean DC rails

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Confirm availability status as distribution channels may list limited stock. Ensure compatibility with existing PCB footprints for the 16-lead SOIC package. Check for RoHS compliance declarations if required by project specifications.

Selection Notes

Select this component when ultralow noise is critical for downstream analog signals. Consider the push-pull topology for higher efficiency compared to linear regulators at moderate loads. Evaluate the 20 kHz to 250 kHz frequency range against external inductor size requirements. Verify that the 1 A output current meets peak load demands without exceeding thermal limits.

Part Context

This part belongs to the LT1533 series of micropower switching regulators. It is designed to replace linear regulators in battery-operated devices where efficiency and noise are primary concerns. The series emphasizes low quiescent current and minimal electromagnetic interference generation.
