- Logic controlled electronic shutdown
Applications
- Power supply switching post regulation
- Series power supply for monitors
- Battery powered systems
Procurement Notes
Verify the specific suffix 'PTR' against the official STMicroelectronics datasheet to confirm package type and tape-and-reel specifications. Ensure the required output voltage matches the fixed or adjustable variant selected. Confirm that the operating temperature range meets system requirements before finalizing procurement.
Selection Notes
Select this component for applications requiring medium current loads with tight dropout constraints. The low ground current makes it suitable for battery-powered designs where efficiency is critical. Verify compatibility with external capacitors if using the adjustable version to ensure stability under all load conditions.
Part Context
The LD29080 is part of STMicroelectronics' LDO regulator portfolio designed for medium current applications. It offers high accuracy and low noise characteristics compared to standard linear regulators. The series supports both fixed and adjustable output configurations to accommodate diverse circuit design needs.
