LD6806TD/36P,125

Overview

The LD6806TD/36P,125 is a low-dropout regulator (LDO) from the LD6806 series manufactured by NXP Semiconductors. It provides a fixed nominal output voltage of 3.6 V with a maximum continuous output current rating of 200 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 60 mV at full load. It utilizes a TSOP5 plastic surface-mounted package (SOT753). Key electrical characteristics include a typical quiescent current of 70 µA in active mode and 1.0 µA in shutdown mode. The regulator incorporates integrated thermal protection, overcurrent protection, and ESD protection rated at 10 kV Human Body Model.

Feature Summary

• Ultra-low dropout performance ensures high efficiency and minimal power dissipation during operation.
• Low noise output design maintains stable voltage regulation for sensitive analog and digital interfaces.
• Integrated enable pin allows precise control of power states with low quiescent current consumption.
• Built-in thermal and overcurrent protection safeguards the device under fault conditions.

Applications

• Mobile phone handsets requiring component miniaturization
• Cordless telephones needing low-voltage supply regulation
• Personal digital devices utilizing analog and digital interfaces

Procurement Notes

Verify that the specific suffix '36P' corresponds to the required 3.6 V fixed output voltage and low-ohmic disabled state configuration. Confirm the 'TD' prefix matches the SOT753 (TSOP5) package requirement for your PCB layout. Ensure compatibility with RoHS and Halogen-free compliance standards if mandated by your manufacturing process specifications.

Selection Notes

Select this component when a compact LDO solution is needed for portable electronics. The SOT753 package offers a small footprint suitable for space-constrained designs. Consider the 3.6 V output level against system requirements. Evaluate the need for the low-ohmic pull-down feature upon disablement versus high-impedance options available in other variants.

Part Context

This part belongs to the LD6806 series of ultra low-dropout regulators designed for mobile appliances. The series includes variants with different output voltages and packages such as WLCSP4 and SOT886. The LD6806TD variant specifically denotes the TSOP5 package form factor, distinguishing it from leadless or chip-scale alternatives within the same functional family.
