LD39015M18R

Overview

The LD39015M18R is a fixed-output low dropout linear voltage regulator manufactured by STMicroelectronics. It provides a guaranteed output current of 150 mA with a fixed output voltage of 1.8 V. The device operates within an input voltage range of 1.5 V to 5.5 V and features a typical dropout voltage of 80 mV at a 100 mA load. Quiescent current is specified as 18 μA typ. at no load and 38 μA typ. at full load, with shutdown consumption below 1 μA. Output voltage tolerance is ±2.0% at 25 °C. The regulator includes logic-controlled electronic shutdown, short-circuit constant current limiting, and thermal protection. It is stable with ceramic capacitors and operates from -40 °C to +125 °C.

Feature Summary

Ultra-low dropout voltage performance suitable for battery-powered applications
Logic-controlled electronic shutdown function for extended battery life
Internal short-circuit constant current limiting and thermal protection
Compatible with small ceramic output capacitors

Applications

Mobile phones
Personal digital assistants (PDAs)
Cordless phones
Battery-powered systems

Procurement Notes

Verify the specific suffix 'M18R' corresponds to the 1.8 V fixed output and SOT-23-5 package configuration. Confirm RoHS compliance status through official documentation. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for any recent lifecycle notices regarding obsolescence or recommended replacements.

Selection Notes

Select this component when a fixed 1.8 V rail is required with minimal quiescent current draw. The low noise characteristic makes it suitable for sensitive analog circuits in portable devices. Verify that the input voltage remains above the minimum threshold while accounting for dropout voltage under maximum load conditions. Ensure the application environment stays within the specified operating temperature range.
