Overview
The LD29150PT33 is a fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a stable 3.3V output with a maximum continuous current of 1.5A. The device operates within an input voltage range of up to 14V and features a typical dropout voltage of 400mV at full load. It incorporates internal thermal overload and short-circuit current protection mechanisms. The component is housed in a surface-mount PPAK package, suitable for applications requiring high accuracy and efficient power management in compact designs.
Feature Summary
- Guarantees a maximum output current of 1.5A with high regulation accuracy.
- Features very low dropout voltage characteristics for efficient power usage.
- Includes integrated thermal overload and short-circuit current protection.
Applications
- Power supply switching post-regulation
- Series power supplies for monitors and televisions
- Computer systems requiring stable voltage rails
Procurement Notes
Verify the specific suffix 'PT33' against official STMicroelectronics documentation to confirm the exact package type and fixed output voltage configuration. Ensure compatibility with the target PCB footprint and thermal requirements before finalizing procurement orders.
Selection Notes
Select this component when a fixed 3.3V rail is required with high current capability. Consider the PPAK package for its thermal performance and space efficiency compared to traditional through-hole options. Verify that the input voltage does not exceed the maximum rating to ensure reliable operation.
Part Context
This part belongs to the LD29150 series of high-current, high-accuracy low-dropout regulators. The series is designed for demanding applications where maintaining voltage stability under heavy loads is critical. The LD29150PT33 specifically offers a fixed 3.3V output, distinguishing it from adjustable variants within the same family.
Replacement Considerations
LD29150P2T33R: A similar fixed 3.3V regulator in a P2PAK package. Verify pinout and thermal pad configurations for direct replacement suitability.
