LD29150P2T33R

Overview

The LD29150P2T33R is a positive fixed linear low-dropout voltage regulator manufactured by STMicroelectronics. It provides a fixed output voltage of 3.3V with a maximum continuous output current of 1.5A. The device operates within an input voltage range from 2.5V to 14V and features a typical dropout voltage of 400mV at full load. It incorporates internal thermal overload protection and current limiting. The component is housed in a P2PAK surface-mount package, which includes four leads and a tab for enhanced thermal dissipation.

Feature Summary

Provides a stable fixed 3.3V output with high accuracy
Delivers up to 1.5A output current capability
Features very low dropout voltage characteristics
Includes internal thermal and current limit protections

Applications

Power supply switching post regulation
Series power supply for monitors
Battery powered systems requiring low dropout
Computer systems power distribution

Procurement Notes

Verify the specific suffix 'P2T33R' to confirm the fixed 3.3V output variant and P2PAK packaging. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for obsolescence notices or lifecycle changes before finalizing procurement plans. Ensure the ordering quantity matches the standard reel size if tape-and-reel delivery is required.

Selection Notes

Select this component when a fixed 3.3V rail is needed with high current capacity. The P2PAK package offers superior thermal performance compared to standard DPAK packages. Consider the 14V maximum input voltage limit during system design. Verify that the application does not require adjustable output voltages, as this part is fixed.

Part Context

This part belongs to the LD29150 series of high-current, high-accuracy low-dropout regulators. The series is designed for applications demanding tight voltage regulation under heavy loads. The P2PAK variant specifically addresses thermal management needs in compact surface-mount designs.
