LT1506IS8-3.3#TRMPBF

Overview

The LT1506IS8-3.3#TRMPBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc., housed in an 8-SOIC package with a width of 3.90mm. It provides a fixed positive output voltage of 3.3V and supports a maximum output current of 4.5A. The device operates with an input voltage range from 4V to 15V and features a fixed switching frequency of 500kHz. Designed for surface-mount installation, it functions as a buck converter within the LT1507 series family.

Feature Summary

Monolithic step-down switching regulator topology
Fixed 3.3V positive output configuration
Integrated 4.5A switch capability
500kHz fixed switching frequency operation

Applications

General purpose DC-DC conversion
Post-regulation for higher voltage rails
Battery-powered systems requiring efficient step-down

Procurement Notes

Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and temperature grade specifications. Ensure the ordering part number matches the required 8-SOIC variant. Cross-reference the manufacturer's latest datasheet to validate RoHS compliance status and any recent product change notices affecting this specific revision.

Selection Notes

Select this component when a fixed 3.3V output at up to 4.5A is required from an input supply between 4V and 15V. The 500kHz frequency allows for compact external component sizing compared to lower-frequency alternatives. Consider the SOIC-8 package constraints for thermal management and PCB layout requirements relative to the expected load current and ambient operating conditions.

Part Context

This part belongs to the LT1506/LT1507 family of high-current switching regulators. It shares architectural similarities with the LT1507 but offers higher current capacity. The IS8 designation indicates the industrial temperature range and SOIC-8 package style, distinguishing it from other package options or commercial grade variants within the same functional family.
