LM1085IS-3.3/NOPB

Overview

The LM1085IS-3.3/NOPB is a positive fixed-output low-dropout linear regulator manufactured by Texas Instruments. It provides a stable 3.3V output with a maximum continuous current of 3A. The device supports an input voltage range from 2.6V to 18V and operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a typical dropout voltage of 1.3V at full load, a maximum static current of 10mA, and a power supply rejection ratio (PSRR) of 72dB at 120Hz. It is housed in a surface-mount D2PAK-3 (TO-263) package.

Feature Summary

Integrated thermal overload and current limit protection for enhanced reliability under fault conditions
Low dropout voltage characteristic enabling efficient regulation with minimal input-to-output voltage differential
High power supply rejection ratio ensuring effective suppression of input ripple and noise

Applications

Point-of-load regulation in embedded systems requiring stable 3.3V rails
Battery-powered equipment utilizing linear regulation for low-noise performance
General-purpose power management in industrial control modules

Procurement Notes

Verify the specific suffix 'NOPB' to confirm lead-free and RoHS compliance status as per manufacturer specifications. Ensure the ordering part number matches the exact package type and output voltage variant required for the design. Cross-reference datasheet revisions to confirm pinout consistency and recommended operating conditions before finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.3V output is required with up to 3A load capability. It is suitable for applications where input voltages remain above 2.6V and do not exceed 18V. Consider the thermal dissipation requirements associated with the D2PAK package and the expected voltage drop across the regulator during operation.

Part Context

This device belongs to the LM1085 family of adjustable and fixed-output regulators. It shares functional similarities with other members like the LM1085IS-ADJ but offers a fixed voltage configuration. The series is designed for general-purpose linear regulation tasks requiring moderate current handling and robust protection features.
