LD29300P2M33

Overview

The LD29300P2M33 is a fixed-output low-dropout voltage regulator from STMicroelectronics, providing a nominal 3.3V output with ±1% tolerance at 25°C. It supports a guaranteed continuous output current of up to 3A and features an internal logic-controlled electronic shutdown function. The device operates within a DC input voltage range of 2.5V to 30V and maintains functionality across a junction temperature range of -40°C to +125°C.

Feature Summary

• High accuracy regulation with tight output voltage tolerance
• Integrated thermal and current limiting protection mechanisms
• Logic-controlled electronic shutdown capability for power management

Applications

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

Procurement Notes

Verify the specific package variant (P2PAK) and suffix against official STMicroelectronics documentation before procurement. Confirm that the fixed 3.3V version matches the required application voltage. Ensure compatibility with the intended PCB footprint and thermal dissipation requirements for the P2PAK housing.

Selection Notes

Select this component when a precise 3.3V rail is needed under heavy load conditions. The P2PAK package offers surface-mount convenience with adequate thermal performance. Consider the internal shutdown feature if system standby control is required. Verify input voltage stability to ensure operation remains within the specified dropout limits during peak current draw.

Part Context

This part belongs to the LD29300 series of very low dropout regulators designed for high-current applications. The series includes various fixed voltage options and adjustable versions. The P2PAK designation indicates a specific surface-mount package configuration suitable for automated assembly and compact board layouts.
