LD6806TD/20P,125

Overview

The LD6806TD/20P,125 is a fixed-output Low-DropOut regulator from the NXP LD6806 series. It provides a nominal output voltage of 2.0 V with a maximum continuous output current 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 (SOT753) surface-mounted package.

Feature Summary

• Integrated pull-down switching transistor ensures a low-ohmic output state when disabled
• Ultra-low noise performance with typical RMS output noise of 30 µV over the 10 Hz to 100 kHz bandwidth
• Includes thermal protection and current limiter for enhanced operational safety

Applications

• Analog and digital interfaces requiring lower than standard supply voltages in mobile appliances
• Mobile phone handsets and personal digital devices requiring component miniaturization
• Cordless telephones and media players

Procurement Notes

Verify that the specific suffix '20' corresponds to the required 2.0 V output voltage configuration. Confirm the 'P' designation indicates the presence of the internal pull-down transistor for the disabled state. Ensure the TSOP5 package variant matches the PCB footprint requirements.

Selection Notes

Select this component for designs prioritizing low quiescent current and minimal noise in portable electronics. The active HIGH enable pin allows for precise power management control. Verify that the external load capacitance meets the minimum stability requirement of 0.7 µF.

Part Context

This part belongs to the LD6806 series of ultra low-dropout regulators manufactured by NXP Semiconductors. The series offers various output voltages ranging from 1.2 V to 3.6 V across multiple package types including WLCSP4, SOT886, and SOT753. All devices share the same monolithic silicon regulator design.

Replacement Considerations

LD6806TD/25P,125: Same package and feature set but provides a 2.5 V output instead of 2.0 V.
