LDK130PU25R

Overview

The LDK130PU25R is a fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a nominal output voltage of 2.5V with a maximum continuous output current of 300mA. The device operates within an input voltage range of 1.9V to 5.5V and features a typical dropout voltage of 100mV at 100mA load, with a maximum specified dropout of 400mV at full load. It incorporates logic-controlled shutdown functionality, reducing quiescent current to below 1μA in off mode, while maintaining a typical active quiescent current of 60μA. The regulator includes internal short-circuit constant current limiting and thermal protection mechanisms.

Feature Summary

Logic-controlled electronic shutdown function enables deep sleep mode for ultra-low power consumption
Internal protection circuits provide short-circuit current limiting and thermal overload safety
Stabilized operation compatible with small ceramic output capacitors

Applications

Low-power battery-powered consumer electronics requiring precise voltage regulation
Post-regulation stages in automotive electronic systems
Noise-sensitive sensor power supplies

Procurement Notes

Verify the specific suffix 'PU' confirms the DFN-6 package configuration and tape-and-reel shipping format. Confirm RoHS compliance status and ensure the ordering code matches the required 2.5V fixed output variant. Cross-reference the manufacturer's latest datasheet for any manufacturing changes or pinout definitions prior to final procurement.

Selection Notes

Select this component when a compact surface-mount solution is required for stable 2.5V generation from single-cell lithium sources. The low quiescent current makes it suitable for energy-constrained designs. Ensure the application does not require adjustable output voltages, as this model is factory-set to a fixed level.

Part Context

This part belongs to the LDK130 series of low-dropout regulators designed for high efficiency and minimal noise. The series offers various fixed output voltages and packaging options, including SOT23-5L and DFN packages. The LDK130PU25R specifically utilizes the 6-pin DFN footprint to support space-constrained printed circuit board layouts.
