LD29080PT15R

Overview

The LD29080PT15R is a fixed-output low-dropout linear voltage regulator manufactured by STMicroelectronics. It provides a stable 1.5 V output with a maximum load current of 800 mA. The device features a typical dropout voltage of 400 mV at full load and maintains high accuracy with ±1% tolerance at 25 °C. It operates within an input voltage range up to 13 V and includes internal protections against overcurrent and thermal overload.

Feature Summary

• Ultra-low dropout voltage performance for efficient power regulation
• Logic-controlled electronic shutdown capability for system power management
• Internal current limiting and thermal protection mechanisms

Applications

• Post-regulation in switching power supply architectures
• Series power supplies for monitors, VCRs, and televisions
• Battery-powered systems requiring extended runtime
• Computer systems needing stable local voltage rails

Procurement Notes

Verify the specific suffix 'PT15R' to confirm the 1.5 V fixed output and PPAK package variant. Ensure compatibility with surface-mount assembly processes. Confirm RoHS compliance status for environmental regulations. Validate that the 800 mA current rating meets the design requirements under expected thermal conditions.

Selection Notes

Select this component when a precise 1.5 V rail is required with moderate current demands. The low ground current makes it suitable for battery-operated devices where quiescent power consumption is critical. Consider the PPAK package for its thermal dissipation capabilities in compact designs compared to smaller packages.

Part Context

This part belongs to the LD29080 series of medium-current, high-accuracy LDO regulators. The series offers both fixed and adjustable output options. The LD29080 family is designed for applications requiring tight voltage regulation and low noise, serving as a reliable solution for powering sensitive analog and digital circuits in consumer electronics.

Replacement Considerations

Check for direct pin-compatible alternatives within the same LD29080 family with different output voltages or packages. Verify if newer generations from STMicroelectronics offer improved thermal performance or lower dropout characteristics while maintaining the same footprint and electrical specifications.
