LD29300V15

Overview

The LD29300V15 is a fixed-output low-dropout voltage regulator providing 1.5 V with ±1% tolerance at 25°C. It guarantees an output current up to 3 A and features a typical dropout voltage of 400 mV at full load. The device includes internal current and thermal limiting, logic-controlled electronic shutdown, and operates within a junction temperature range of -40 to 125°C.

Feature Summary

• High accuracy fixed output voltage regulation
• Logic controlled electronic shutdown capability
• Internal current and thermal protection limits

Applications

• Power supply switching post regulation
• Series power supply for monitors
• Computer systems
• Battery powered systems

Procurement Notes

Verify the specific package variant (TO-220, D2PAK, or P2PAK) required for your design, as the base model number does not specify it. Confirm that the input voltage remains below 14 V to prevent automatic shutdown. Ensure the selected component matches the exact 1.5 V fixed output requirement.

Selection Notes

Select this regulator for applications requiring high current delivery with minimal voltage drop. Verify that the input voltage provides sufficient headroom above 1.5 V while staying under the absolute maximum rating. Consider the thermal resistance of the chosen package to ensure safe operation under maximum load conditions.

Part Context

This component belongs to the LD29300 series of very low dropout voltage regulators manufactured by STMicroelectronics. The series offers various fixed output voltages and adjustable versions across multiple packages including TO-220, D2PAK, and P2PAK variants.

Replacement Considerations

Compatible substitutes include other LD29300 series parts with different output voltages or packages, such as LD29300D2T15 or LD29300P2M15, provided the electrical characteristics match the system requirements.
