LD29300P2MTR

Overview

The LD29300P2MTR is a high-current, high-accuracy low-dropout voltage regulator manufactured by STMicroelectronics. It provides a guaranteed output current of up to 3 A with a typical dropout voltage of 400 mV at full load. The device features very low ground current and maintains high accuracy within ±1% at 25°C. It operates with an input voltage range from 2.5 V to 30 V and supports surface mount installation in a 6-pin package. The maximum operating temperature reaches 125 °C.

Feature Summary

• Very low dropout voltage for efficient power regulation under heavy loads
• High accuracy output voltage stability across operating conditions
• Integrated internal current limiting and thermal shutdown protection
• Logic-controlled electronic shutdown capability for system power management

Applications

• Power supply switching post-regulation
• Series power supply for monitors and televisions
• Computer systems requiring stable high-current rails
• Battery-powered systems demanding low dropout performance

Procurement Notes

Verify the specific suffix 'P2MTR' against the official datasheet to confirm pinout configuration and package type. Ensure the required output voltage variant matches the application design, as the base family includes fixed and adjustable options. Confirm RoHS compliance status and check for any end-of-life notices or alternative recommendations from the manufacturer before finalizing procurement.

Selection Notes

Select this component when designing circuits that require high output current capability combined with minimal voltage drop. The low ground current makes it suitable for battery-operated devices where efficiency is critical. Consider the thermal performance and heat dissipation requirements due to the 3 A output capacity. Verify that the input voltage range aligns with the source power supply specifications.

Part Context
