LDK130M18RY

Overview

The LDK130M18RY is an automotive-grade low dropout (LDO) linear voltage regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 1.8 V with a maximum output current of 300 mA. The device operates within an input voltage range of 1.9 V to 5.5 V and features a typical dropout voltage of 100 mV at 100 mA load. It exhibits a low quiescent current of 30 µA, which reduces to less than 1 µA in shutdown mode via logic control. The component is qualified under AEC-Q100 standards for Grade 1 applications and is housed in a SOT23-5L package.

Feature Summary

Automotive qualification compliant with AEC-Q100 Grade 1 standards
Logic-controlled electronic shutdown function for ultra-low power consumption
Internal short-circuit constant current limiting and thermal protection mechanisms

Applications

Low-power battery-powered automotive systems
Automotive infotainment subsystems
Body electronics and convenience modules

Procurement Notes

Verify the specific suffix 'RY' against the manufacturer's official datasheet to confirm the exact packaging configuration and reel specifications. Ensure the selected variant matches the required automotive grade and temperature range specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring stable power delivery for sensitive automotive loads. The fixed 1.8 V output eliminates the need for external resistors, simplifying the design. Verify that the input voltage remains within the 1.9 V to 5.5 V operational window to maintain regulation and ensure adequate headroom for the specified load current requirements.

Part Context

This part belongs to the LDK130 series of low-dropout regulators designed specifically for automotive environments. The series offers various fixed output voltages ranging from 0.8 V to 3.5 V. The M18 designation indicates the 1.8 V fixed output version, while the SOT23-5L package provides a compact footprint suitable for space-constrained automotive PCB layouts.
