LD39030SJ10R

Overview

The LD39030SJ10R is a fixed-output linear low-dropout regulator manufactured by STMicroelectronics, providing a stable 1V output with a maximum current capacity of 300mA. It operates within an input voltage range of 1.5V to 5.5V and features a typical dropout voltage of 200mV at full load. The device incorporates ultra-low quiescent current characteristics, consuming approximately 20µA at no load and less than 1µA in shutdown mode. Key electrical specifications include a power supply rejection ratio of 62dB at low frequencies and an output voltage tolerance of ±2.0% at 25°C. It is housed in a compact 4-flipchip package measuring 0.79x0.79mm.

Feature Summary

Ultra-low dropout voltage design for efficient power management
Very low quiescent current consumption for battery-powered applications
Low noise performance suitable for sensitive analog circuits
Integrated enable logic control for electronic shutdown

Applications

Low power battery-operated portable devices
Mobile connectivity sensor nodes
Smart hub solutions requiring stable low-voltage rails

Procurement Notes

Verify component status as the LD39030SJ10R is listed as obsolete and no longer manufactured by STMicroelectronics. Confirm availability through authorized distributors or alternative sources. Ensure compatibility with existing PCB layouts when sourcing replacements. Check for RoHS compliance and moisture sensitivity levels before procurement. Validate that substitute components meet original electrical specifications.

Selection Notes

Select this component for designs requiring a fixed 1V rail with moderate current demands up to 300mA. Consider its flipchip packaging for space-constrained applications. Evaluate the low noise profile if powering RF or audio sections. Verify input voltage stability remains within the 1.5V to 5.5V range. Assess thermal requirements given the small package size and potential heat dissipation under load.

Part Context

This part belongs to the LD39030 family of low-noise voltage regulators from STMicroelectronics. It shares core architectural features with other variants in the series but differs in output voltage and packaging. The SJ suffix indicates the specific flipchip package type. This family targets applications needing high accuracy and low power consumption in minimal footprints.
