Overview
The LD29150PT15R is a positive fixed-output linear voltage regulator IC manufactured by STMicroelectronics. It provides a fixed output voltage of 1.5V with a maximum output current capability of 1.5A. The device utilizes a PPAK surface-mount package and operates within an ambient temperature range of -40°C to +125°C. Key electrical specifications include a typical dropout voltage of 400mV at full load, a maximum input voltage rating of 14V, and a quiescent current of 180µA. It incorporates internal protection features such as overcurrent limiting and thermal shutdown.
Feature Summary
- Very low dropout voltage characteristic for efficient power regulation
- Guaranteed high output current capability up to 1.5A
- Integrated overcurrent and thermal protection mechanisms
- Fixed output voltage configuration for simplified circuit design
Applications
- Power supply switching post-regulation
- Series power supplies for monitors and televisions
- Battery-powered electronic systems
- Computer system power distribution
Procurement Notes
Verify the specific suffix 'PT15R' to confirm the 1.5V fixed output and PPAK packaging variant. Confirm RoHS compliance status and lead-free characteristics against the latest manufacturer documentation. Ensure the procurement source provides valid traceability for this discontinued or active component series depending on current market availability.
Selection Notes
Select this component when a stable 1.5V rail is required with high current demand in a compact form factor. The PPAK package offers thermal advantages for surface-mount applications. Consider the 14V maximum input rating and dropout characteristics relative to the input source voltage to ensure proper regulation under all operating conditions.
Part Context
This part belongs to the LD29150 series of very low drop voltage regulators from STMicroelectronics. The series is designed for high-current loads and critical low-dropout systems. Variants differ by output voltage and package type, with the PT15R specifically denoting the 1.5V fixed output in the PPAK housing.
Replacement Considerations
Cross-reference with other LD29150 variants for different voltage outputs if system requirements change. Verify pin compatibility and thermal performance when substituting with packages like DPAK or TO-252.
