LD6806TD/22H,125

Overview

The LD6806TD/22H,125 is a fixed-output Low-DropOut regulator from the NXP LD6806 series. It provides a nominal output voltage of 2.2 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

• Ultra-low dropout voltage performance for high efficiency
• Low noise operation suitable for sensitive analog circuits
• High-ohmic (three-state) output when disabled
• Integrated thermal protection and current limiting

Applications

• Mobile phone handsets
• Cordless telephones
• Personal digital devices
• Media players

Procurement Notes

Verify the specific suffix 'H' indicates the high-ohmic output state variant. Confirm the 'TD' designation corresponds to the SOT753 TSOP5 package type. Ensure the ',125' suffix matches the required RoHS compliance and environmental specifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a compact footprint and low quiescent current. The high-ohmic output state is critical for bus sharing applications where the regulator must effectively disconnect from the load during shutdown. Verify that the external capacitor meets the minimum ESR requirements for stability.

Part Context

This part belongs to the LD6806 series of ultra low-dropout regulators manufactured by NXP Semiconductors. The series includes variants in WLCSP4, SOT886, and SOT753 packages, offering various fixed output voltages between 1.2 V and 3.6 V. The technology is designed for miniaturization in portable consumer electronics.
