LS320 SOT-23 3L ROHS

Overview

The LS320 is a low-dropout linear voltage regulator manufactured by Linear Integrated Systems, Inc., housed in a compact SOT-23 three-lead package. It provides a fixed output voltage of 3.0V with a maximum load current capability of 200mA. The device operates from an input voltage range spanning 2.5V to 18V and features a typical dropout voltage of 100mV at full load. Designed for stability with ceramic capacitors, it includes integrated short-circuit current limiting, thermal shutdown, and safe operating area protection. The unit supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

Low dropout operation enables efficient power regulation with minimal voltage headroom requirements
Integrated protection mechanisms include short-circuit current limiting and thermal shutdown
Stabilized for use with small ceramic output capacitors to minimize board space
Logic-controlled electronic shutdown allows for ultra-low quiescent current consumption

Applications

Battery-powered portable electronics requiring low quiescent current
Embedded systems needing stable 3.0V logic supply rails
Communication equipment and computer peripherals
Industrial control modules operating in wide temperature environments

Procurement Notes

Verify the manufacturer designation as Linear Integrated Systems, Inc., distinct from other entities using similar model numbers. Confirm the specific suffix indicates RoHS compliance and the SOT-23 3L package variant. Ensure the datasheet matches the 200mA output current specification and 3.0V fixed output voltage. Cross-reference the thermal characteristics and protection features against the official component documentation to confirm suitability for the intended application environment.

Selection Notes

Select this component when a fixed 3.0V rail is required with moderate current demands up to 200mA. It is suitable for designs prioritizing low dropout performance and compatibility with ceramic output capacitors. Consider the wide input voltage range and robust protection features for industrial or automotive applications. Verify that the SOT-23 package fits the available PCB footprint constraints.

Part Context

This part belongs to the family of low-dropout linear regulators designed for battery-operated devices. It offers a balance of performance and size, utilizing a standard SOT-23 package. The device integrates essential protections to ensure reliability in various power management scenarios.
