LD29150PT

Overview

The LD29150PT is a high-current, high-accuracy low-dropout (LDO) voltage regulator from the STMicroelectronics LD29150 series. It provides a guaranteed output current of up to 1.5 A with a typical dropout voltage of 400 mV at full load. The device features very low ground current and offers both fixed and adjustable output voltage options with an accuracy of ±1% at 25 °C. It includes internal current limiting and thermal shutdown protection for robust operation.

Feature Summary

• Very low dropout voltage characteristic enabling efficient power management in critical systems
• Guaranteed high output current capability suitable for demanding loads
• Integrated internal current limit and thermal limit for enhanced reliability

Applications

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

Procurement Notes

Verify the specific suffix against official datasheets to confirm output configuration, as the base part number covers multiple variants. Confirm package type and temperature range requirements match the intended application environment before procurement.

Selection Notes

Select this component when high current delivery and minimal voltage drop are required. Ensure input voltage exceeds the minimum requirement for the desired output level. Consider the available fixed or adjustable versions based on circuit design needs.

Part Context

This component belongs to the LD29150 series of LDO regulators designed for applications requiring high current and low dropout performance. The series is characterized by its ability to maintain regulation under heavy loads while minimizing power loss across the regulator.

Replacement Considerations

Check for compatible parts within the same LD29150 family that offer similar current ratings and dropout characteristics. Verify pin compatibility and thermal performance if substituting with other manufacturers' LDOs.
