Overview
The LD29300D2M50 is a fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a nominal output voltage of 5.0 V with a guaranteed maximum output current of 3 A. The device operates within an input voltage range up to 30 V, though automatic shutdown occurs above 14 V. It features a typical dropout voltage of 0.4 V at full load and maintains high accuracy with ±1% tolerance at 25 °C. Integrated protections include internal current limiting and thermal shutdown. The component is housed in a D2PAK surface-mount package.
Feature Summary
- Guarantees high output current capability up to 3 A for demanding loads
- Features very low dropout voltage characteristics for efficient power management
- Includes logic-controlled electronic shutdown functionality for system control
- Provides internal protection against overcurrent conditions and excessive temperature
Applications
- Power supply switching post regulation
- Series power supply for monitors
- Series power supply for VCRs and TVs
- Computer systems
- Battery-powered systems
Procurement Notes
Verify the specific suffix 'D2M' confirms the D2PAK package style and 5.0 V fixed output configuration. Confirm that the ordering code matches the manufacturer's official list for the D2PAK variant. Ensure compatibility with required thermal dissipation standards for the target application environment.
Selection Notes
Select this regulator when a stable 5.0 V rail is required with high current delivery capabilities. Consider the D2PAK package for its thermal performance in surface-mount designs. Evaluate the input voltage constraints, noting the automatic shutdown feature if inputs exceed 14 V. Verify that the low dropout characteristic meets the efficiency requirements of the downstream circuitry.
Part Context
This component belongs to the LD29300 series of high-current, high-accuracy low-dropout regulators. The series includes various fixed voltage options and adjustable versions. The LD29300D2M50 specifically designates the 5.0 V fixed output version packaged in the D2PAK format, distinguishing it from TO-220 or P2PAK variants within the same functional family.
