LD39130SJ18R

Overview

The LD39130SJ18R is a fixed-output low-dropout linear regulator manufactured by STMicroelectronics. It provides a stable 1.8 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 quiescent current of 45 uA, power supply rejection ratio (PSRR) of 70 dB, line regulation of 0.02 %/V, and load regulation of 0.004 %/mA. It supports operation from -40°C to +125°C and utilizes a FlipChip-4 package.

Feature Summary

Provides a fixed 1.8 V output with 300 mA continuous current capability
Features ultra-low quiescent current for efficient battery-powered applications
Includes internal protection mechanisms such as overcurrent limiting and thermal shutdown
Operates reliably across a wide industrial temperature range

Applications

Portable electronic devices requiring stable low-voltage power rails
Battery-operated systems prioritizing energy efficiency
Embedded circuits needing noise-sensitive regulated power supplies

Procurement Notes

Verify the specific suffix '18R' confirms the 1.8 V fixed output voltage during procurement. Confirm the FlipChip-4 package type matches your PCB footprint requirements. Ensure compatibility with SMD/SMT assembly processes. Check for RoHS compliance status if required by your manufacturing standards. Validate that the operating temperature range meets your environmental conditions.

Selection Notes

Select this component when a precise 1.8 V rail is required with minimal static power consumption. Consider its small FlipChip-4 footprint for space-constrained designs. Evaluate its 300 mA output limit against peak load demands. Assess the 70 dB PSRR suitability for noise-sensitive analog sections. Compare dropout characteristics against minimum input voltage availability in the system.

Part Context

This part belongs to the LD39130S series of low-dropout regulators from STMicroelectronics. It is categorized under PMIC - Power Management ICs. The series is designed for applications demanding high efficiency and compact form factors. It complements other LDO offerings by providing specific fixed voltage options in a flip-chip configuration.
