LD39130SPU25R

Overview

The LD39130SPU25R is a fixed-output low-dropout linear regulator manufactured by STMicroelectronics. It provides a stable 2.5 V output with a maximum current capacity of 300 mA. The device operates from 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 quiescent current of 45 µA, a power supply rejection ratio (PSRR) of 70 dB at 1 kHz, and an output tolerance of 1%. It incorporates protection mechanisms including overcurrent limiting, thermal shutdown, and soft-start functionality.

Feature Summary

Integrates automatic Green Mode operation to minimize quiescent current during light-load conditions
Provides high accuracy voltage regulation with 1% output voltage tolerance
Includes comprehensive protection features such as overcurrent limiting, thermal shutdown, and soft-start

Applications

Portable media players
Handheld devices
Battery-powered systems

Procurement Notes

Verify the specific package variant when ordering, as the LD39130S series utilizes different footprints. Confirm that the DFN-6 package matches your PCB layout requirements. Ensure compatibility with the required 2.5 V output level for your target circuit design before finalizing procurement.

Selection Notes

Select this component for applications requiring ultra-low quiescent current and small form factor solutions. The DFN-6 package offers a compact footprint suitable for space-constrained designs. Consider the 300 mA output limit when sizing for peak load currents in portable electronics.

Part Context

This part belongs to the LD39130S family of low-dropout regulators designed for portable applications. The family includes variants with different output voltages and packages, such as the flip-chip LD39130SJ series. The SP suffix indicates the DFN-6 package configuration used in this specific model.
