LDL112PV10R

Overview

The LDL112PV10R is a low-dropout linear regulator manufactured by STMicroelectronics, designed to provide a maximum output current of 1.2 A with a typical dropout voltage of 300 mV at 1 A load. It operates within an input voltage range of 1.6 V to 5.5 V and delivers a fixed 1.0 V output. The device features a low quiescent current of 35 μA (typical) at no-load and less than 1 μA in shutdown mode. It includes reverse current protection, internal current limit, and thermal protection, ensuring stability with a 1 μF ceramic output capacitor.

Feature Summary

• Reverse current protection prevents backflow from output to input
• Logic-controlled electronic shutdown for ultra-low power consumption
• Compatible with small ceramic output capacitors for stability
• Integrated overcurrent and thermal protection mechanisms

Applications

• Low power battery-powered portable devices
• Embedded systems requiring stable 1.0 V logic supply
• Portable electronics with strict power management needs

Procurement Notes

Verify the specific suffix 'V10' confirms the fixed 1.0 V output voltage during procurement. Confirm package type matches design requirements, typically DFN-6 for this series variant. Ensure compatibility with 1 μF ceramic output capacitors as specified in official documentation. Check RoHS compliance status if required for specific manufacturing standards.

Selection Notes

Select this component when a fixed 1.0 V output is required with high current capability up to 1.2 A. Consider its low quiescent current for battery life extension in portable applications. Verify that the input voltage range of 1.6 V to 5.5 V aligns with the system power source. Ensure the design accommodates the necessary ceramic output capacitance for stability.
