Overview
The LD29080DT25R is a fixed-output low-dropout linear voltage regulator from STMicroelectronics, providing a stable 2.5V output with a maximum current capacity of 800mA. It operates within an input voltage range of 2.5V to 13V and features a typical dropout voltage of 400mV at full load. The device incorporates internal current limiting and thermal shutdown protection for enhanced reliability. Designed for surface-mount applications, it utilizes the DPAK (TO-252) package configuration.
Feature Summary
- Guarantees up to 800mA output current capability
- Features very low ground current consumption
- Includes logic-controlled electronic shutdown function
- Provides internal current and thermal limit protection
Applications
- Power supply switching post regulation
- Series power supply for monitors
- Battery powered systems
Procurement Notes
Verify the specific suffix 'DT' confirms the DPAK package type and '25' indicates the 2.5V fixed output voltage. Confirm RoHS compliance status as manufacturing processes may evolve. Check for active production status or obsolescence notices prior to finalizing design-in decisions.
Selection Notes
Select this component when a medium-current LDO with low dropout characteristics is required. Ensure the input voltage remains within the specified 13V maximum limit. Consider the thermal performance in the DPAK package for high ambient temperature environments.
Part Context
This part belongs to the LD29080 series of medium current, high accuracy low-dropout regulators. The series offers both fixed and adjustable output options, designed for applications requiring precise voltage regulation under varying load conditions.
Replacement Considerations
Consult official documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully before substituting.
