Overview
The LD29300P2M50R is a fixed-output linear voltage regulator from the STMicroelectronics LD29300 series, providing a nominal output of 5.0 V with ±1% tolerance at 25°C. It supports a guaranteed continuous output current up to 3 A and features a very low dropout voltage of typically 0.4 V at full load. The device includes logic-controlled electronic shutdown functionality and internal thermal and current limiting protections.
Feature Summary
- Fixed 5.0 V output with high accuracy
- Logic-controlled electronic shutdown
- Internal current and thermal protection
Applications
- Power supply switching post regulation
- Series power supply for monitors
- Computer systems
- Battery-powered systems
Procurement Notes
Verify the specific package variant (P2PAK) and suffix against official datasheets before ordering. Confirm that the fixed 5.0 V version matches the design requirements, as other voltages exist in the series. Ensure compatibility with the required input voltage range and thermal management solutions for the target application environment.
Selection Notes
Select this component when a stable 5.0 V rail is needed for loads up to 3 A. Consider the P2PAK package for surface-mount assembly where thermal dissipation is managed via the PCB copper area. Verify that the input voltage remains within the safe operating area to prevent automatic shutdown if exceeding 14 V without proper heat sinking.
Part Context
This part belongs to the LD29300xx family of high-current, low-dropout regulators. The series offers various fixed output voltages and an adjustable version. The LD29300P2M50R specifically denotes the 5.0 V fixed output in the P2PAK surface-mount package, designed for applications requiring efficient power delivery with minimal voltage drop.
Replacement Considerations
Compatible substitutes include other LD29300 variants such as LD29300D2M50R or LD29300P2T50R, provided the package footprint and pinout are compatible. Verify electrical characteristics and thermal resistance values match the system requirements before substitution.
