Overview
The LD29300P2M80R is a fixed-output low-dropout voltage regulator from the STMicroelectronics LD29300 series. It provides an 8.0 V output with ±1% tolerance at 25°C and supports up to 3 A of guaranteed output current. The device operates within a DC input voltage range of 2.5 V to 30 V and features a typical dropout voltage of 0.4 V at full load. It utilizes a P2PAK surface-mount package and includes internal thermal and current limiting protections.
Feature Summary
- Very low dropout voltage for high efficiency under heavy loads
- High accuracy fixed output voltage with tight tolerance
- Logic-controlled electronic shutdown capability
- Integrated thermal and current limit protection
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 'R' indicates tape-and-reel packaging when sourcing this component. Confirm that the P2PAK package variant matches your board layout requirements. Ensure the 8.0 V fixed output aligns with system design needs, as adjustable or other voltage variants exist within the same series.
Selection Notes
Select this part for applications requiring stable 8.0 V delivery at currents up to 3 A. Consider the P2PAK package for its thermal performance in surface-mount designs. Evaluate the dropout characteristics against your minimum input voltage constraints to ensure proper regulation across the operating temperature range.
Part Context
This component belongs to the LD29300 series of very low drop voltage regulators manufactured by STMicroelectronics. The series offers multiple fixed output voltages and adjustable versions in various packages including TO-220, D2PAK, and P2PAK. The LD29300P2M80R specifically denotes the 8.0 V fixed version in the P2PAK package.
Replacement Considerations
Compatible substitutes include other LD29300 series variants such as LD29300D2M80 or LD29300V80, provided the package type (TO-220 vs P2PAK) and pinout compatibility are verified for your specific application.
