Overview
The LD29080PT25R is a fixed-output low-dropout linear voltage regulator from STMicroelectronics, providing a stable 2.5 V output with a maximum load current of 800 mA. It features a typical dropout voltage of 400 mV at full load and maintains high accuracy with ±1% tolerance at 25 °C. The device incorporates internal current limiting and thermal shutdown protection to ensure operational safety under fault conditions. Designed for surface-mount assembly, it utilizes the PPAK package configuration.
Feature Summary
- Guarantees up to 800 mA output current capability
- Features very low dropout voltage characteristics
- Includes logic-controlled electronic shutdown function
- Provides internal current and thermal limit protections
Applications
- Power supply switching post regulation
- Series power supply for monitors
- Battery powered systems
Procurement Notes
Verify the specific suffix 'PT25R' against official manufacturer documentation to confirm the exact output voltage and package type. Ensure compatibility with required input voltage ranges and thermal management strategies for the intended application environment before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring medium current delivery with tight voltage accuracy. Consider its low ground current and small dropout voltage as critical advantages for battery-powered or efficiency-sensitive designs where standard regulators may exhibit excessive power loss.
Part Context
This part belongs to the LD29080 series of medium current, high accuracy low-dropout voltage regulators. The series is designed for loads requiring reliable regulation with minimal voltage drop across the device, distinguishing it from higher current variants like the LD29300 or ultra-low current models.
Replacement Considerations
Consult official substitution lists for verified equivalents. Generic replacements may not match the specific dropout characteristics or shutdown logic control features documented for this series.
