LD6806TD/13P,125

Overview

The LD6806TD/13P,125 is a fixed-output Low-DropOut regulator from the NXP LD6806 series. It provides a nominal output voltage of 1.3 V with a maximum continuous output current of 200 mA and peak currents up to 300 mA. The device operates within an input voltage range of 2.3 V to 5.5 V. It features ultra-low dropout characteristics, low quiescent current in shutdown mode, and integrated thermal protection and current limiting. The component is housed in a TSOP5 (SOT753) surface-mounted package.

Feature Summary

• Low-ohmic output stage when disabled via internal pull-down switching transistor
• Integrated temperature watchdog for thermal protection
• Built-in current limiter for overload protection
• High ESD protection capability

Applications

• Analog and digital interfaces requiring lower than standard supply voltage in mobile appliances
• Mobile phone handsets
• Cordless telephones
• Personal digital devices

Procurement Notes

Verify that the specific suffix '13P' corresponds to the 1.3 V fixed output voltage variant with low-ohmic disabled state functionality as documented in the official ordering information tables. Confirm the 'TD' designation matches the SOT753 TSOP5 plastic surface-mounted package outline. Ensure the '125' suffix aligns with the required environmental compliance specifications.

Selection Notes

Select this component for applications requiring precise 1.3 V regulation from a 2.3 V to 5.5 V source. The low-ohmic disabled state distinguishes it from high-ohmic variants, making it suitable where a defined low impedance is required at the output during shutdown. Consider the thermal resistance characteristics of the TSOP5 package for heat dissipation requirements.

Part Context

This part belongs to the LD6806 series of ultra low-dropout regulators designed for component miniaturization. The series includes various packages such as WLCSP4, SOT886, and SOT753. The 'P' suffix indicates the presence of a pull-down switching transistor at the output pin, differentiating it from 'H' suffix devices which exhibit a high-ohmic state when disabled.

Replacement Considerations

LD6806TD/13H,125: Identical package and electrical ratings but features a high-ohmic (3-state) output instead of a low-ohmic pull-down when disabled.
