LD39130SJ41R

Overview

The LD39130SJ41R is a fixed-output low-dropout linear regulator manufactured by STMicroelectronics. It provides a stable 4.1 V output with a maximum current capacity of 300 mA. The device operates within an input voltage range of 1.4 V to 5.5 V and features a typical dropout voltage of 300 mV at full load. Key electrical specifications include a power supply rejection ratio (PSRR) of 70 dB, line regulation of 0.02 %/V, and load regulation of 0.004 %/mA. Quiescent current is 55 uA, and the output voltage tolerance is 1 %. It supports operation from -40 °C to +125 °C and utilizes a FlipChip-4 package.

Feature Summary

Ultra-low dropout voltage capability for efficient battery-powered applications
Low quiescent current consumption to extend operational life
High power supply rejection ratio for clean output in noisy environments
Integrated protection against overcurrent and thermal overload

Applications

Portable consumer electronics requiring stable low-voltage rails
Battery-operated medical devices needing precise voltage regulation
Industrial control systems operating in wide temperature ranges
Embedded sensor nodes with strict power budget constraints

Procurement Notes

Verify the specific suffix '41R' confirms the 4.1 V fixed output and reel packaging configuration. Ensure compatibility with FlipChip-4 mounting requirements during PCB layout. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when a fixed 4.1 V rail is required with minimal voltage drop under 300 mA loads. Consider its low quiescent current for battery-sensitive designs. Verify that the FlipChip-4 package fits the available board space and thermal management strategy compared to larger packages.

Part Context

This part belongs to the LD39130S series of low-quiescent-current LDO regulators from STMicroelectronics. The series is designed for portable applications where efficiency and noise performance are critical. The SJ41R variant specifically denotes the 4.1 V output version within this family.
