Overview
The LD29150PT25R is a linear low-dropout voltage regulator manufactured by STMicroelectronics. It provides a fixed positive output voltage of 2.5V with a maximum continuous output current of 1.5A. The device operates within an input voltage range of 2.5V to 14V and features a maximum dropout voltage of 0.7V at full load. It includes internal protection mechanisms for overcurrent and thermal overload conditions, along with logic-controlled electronic shutdown capability.
Feature Summary
- Guarantees high output current up to 1.5A with very low dropout voltage characteristics
- Incorporates internal current limiting and thermal shutdown protection functions
- Supports logic-controlled electronic shutdown for power management
Applications
- Power supply switching post regulation
- Series power supply for monitors and TVs
- Computer systems requiring stable low-voltage rails
- Battery powered systems
Procurement Notes
Verify component status carefully as the LD29150PT25R is listed as obsolete or end-of-life in multiple distributor records. Confirm availability of active alternatives such as the LD29150PTR before finalizing procurement plans. Ensure that any substitute components meet the required electrical specifications and package dimensions for your specific design implementation.
Selection Notes
Select this component when a fixed 2.5V output is required with high current capability in a surface-mount PPAK package. Consider the 14V maximum input voltage limit and the 0.7V dropout characteristic under full load conditions. Evaluate the need for the logic-controlled shutdown feature if system power sequencing is critical to the application design requirements.
Part Context
This part belongs to the LD29150 series of high-current, high-accuracy low-dropout voltage regulators from STMicroelectronics. The series is designed for applications demanding low ground current and minimal voltage drop across the regulator. The PT suffix indicates the specific PPAK surface-mount packaging variant used for this fixed 2.5V output configuration.
Replacement Considerations
The LD29150PTR is identified as a similar replacement option available from STMicroelectronics.
