LD6806F/22P,115

Overview

The LD6806F/22P,115 is a low-dropout regulator (LDO) from NXP with a fixed 2.2 V output and 200 mA current rating. It operates within an input voltage range of 2.3 V to 5.5 V. The device features a typical dropout voltage of 60 mV at full load and includes a pull-down switching transistor for a low-ohmic state when disabled. It provides integrated thermal protection, current limiting, and ESD protection rated at 10 kV Human Body Model.

Feature Summary

• Ultra-low dropout voltage ensures high efficiency and minimal power loss during operation.
• Low noise performance supports sensitive analog and digital interface applications.
• Integrated pull-down transistor maintains a defined low-ohmic output state when the device is disabled.

Applications

• Mobile phone handsets
• Cordless telephones
• Personal digital devices

Procurement Notes

Verify the specific suffix '115' against official documentation to confirm packaging details or tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the SOT886 package dimensions align with your PCB footprint design constraints.

Selection Notes

Select this part for designs requiring a fixed 2.2 V supply in compact mobile form factors. The SOT886 package offers a small footprint suitable for space-constrained layouts. Ensure external capacitors meet the minimum capacitance and ESR requirements for stability across the operating temperature range.

Part Context

This component belongs to the LD6806 series of ultra-low-dropout regulators designed for miniaturization. The series includes variants with different output voltages and packages, such as WLCSP4 and SOT753. The 'P' suffix indicates the presence of a pull-down transistor, distinguishing it from the 'H' variant which offers a high-impedance state when disabled.
