LD29150PTR

Overview

The LD29150PTR is a positive adjustable linear low-dropout voltage regulator manufactured by STMicroelectronics. It provides a guaranteed output current of up to 1.5 A with a maximum input voltage of 30 V and an adjustable output voltage range from 1.23 V to 13.3 V. The device features a typical dropout voltage of 400 mV at full load and includes internal current limiting and thermal shutdown protection. It operates within a junction temperature range of -40°C to 125°C and utilizes a PPAK surface-mount package.

Feature Summary

• Adjustable output voltage configuration with high accuracy
• Integrated electronic shutdown control via logic signal
• Internal protection against overcurrent and excessive temperature

Applications

• Power supply switching post regulation
• Series power supply for monitors and televisions
• Battery powered systems requiring low dropout characteristics

Procurement Notes

Verify the specific suffix 'PTR' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the PPAK package dimensions align with the target PCB footprint and thermal management strategy. Ensure the design accounts for the maximum input voltage limits to prevent device damage during transient conditions.

Selection Notes

Select this component when a high-current, adjustable LDO is needed for applications sensitive to voltage drop across the regulator. The PPAK package offers a compact solution for surface-mount designs. Consider the thermal resistance characteristics of the package when designing for continuous operation at high output currents to ensure reliable performance under varying ambient temperatures.

Part Context

This part belongs to the LD29150 series of high-current, very low dropout voltage regulators. The series is designed for applications requiring stable regulation under heavy loads while minimizing power dissipation through reduced voltage headroom requirements. The LD29150 family supports both fixed and adjustable output configurations to accommodate diverse system voltage needs.

Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers within the same product line or equivalent specifications.
