LD39015M10R

Overview

The LD39015M10R is a fixed-output linear voltage regulator from STMicroelectronics, providing a stable 1V output with a maximum current of 150mA. It operates within an input voltage range of 1.5V to 5.5V and features a typical dropout voltage of 80mV at 100mA load. The device exhibits low quiescent current, typically 18µA at no load, and includes logic-controlled shutdown functionality reducing consumption below 1µA. It incorporates internal short-circuit constant current limiting and thermal protection, ensuring reliability across a wide operating temperature range of -40°C to 125°C.

Feature Summary

Ultra-low dropout voltage capability for efficient power management in battery-powered systems
Logic-controlled electronic shutdown function enabling deep sleep modes with minimal current draw
Integrated protection mechanisms including short-circuit constant current limiting and thermal overload protection

Applications

Mobile phones requiring stable low-voltage rails
Personal digital assistants (PDAs) with strict power constraints
Cordless phones utilizing battery power sources

Procurement Notes

Verify the specific suffix 'M10R' confirms the 1V fixed output voltage and SOT-23-5 packaging configuration. Ensure compatibility with ceramic output capacitors as specified in the datasheet. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before finalizing procurement orders.

Selection Notes

Select this component when a precise 1V output is required with high efficiency under light loads. Consider its low noise characteristics and stability with small ceramic capacitors for space-constrained designs. Evaluate the enable pin functionality if system power sequencing or shutdown control is necessary for the application architecture.
