LD6806F/12P,115

Overview

The LD6806F/12P,115 is an ultra low-dropout regulator (LDO) from NXP Semiconductors. It provides a fixed nominal output voltage of 1.2 V with a maximum 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 the rated load. It utilizes a leadless plastic SOT886 package (XSON6). Key electrical characteristics include a typical quiescent current of 70 µA in active mode and 1.0 µA in shutdown mode. The regulator offers a typical power supply rejection ratio (PSRR) of 55 dB at 1 kHz and a typical RMS output noise voltage of 30 µV over a 10 Hz to 100 kHz bandwidth.

Feature Summary

• Includes temperature watchdog and current limiter for enhanced protection
• Features integrated ESD protection compliant with Human Body Model standards
• Designed for applications requiring component miniaturization

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 the specific suffix '115' against official documentation to confirm packing details, as ordering suffixes may indicate variations in tape and reel specifications or orientation. Confirm that the SOT886 package variant matches the required footprint for the target PCB design. Ensure compliance with RoHS and Halogen-free requirements if mandated by the end-product specifications.

Selection Notes

Select this component when a fixed 1.2 V output is required with high efficiency due to low dropout voltage. The LD6806F/12P,115 is suitable for designs needing a low-ohmic discharge path upon disablement, unlike the high-ohmic variants. Consider the thermal resistance of the SOT886 package and ensure adequate PCB copper area for heat dissipation under maximum load conditions.

Part Context

This part belongs to the LD6806 series of ultra low-dropout regulators manufactured using monolithic silicon technology. The series includes variants with different output voltages ranging from 1.2 V to 3.6 V and packages such as WLCSP4 and SOT753. The 'P' suffix indicates the presence of a pull-down transistor, distinguishing it from the 'H' suffix variants which feature a high-ohmic output state when disabled.

Replacement Considerations

Direct substitutes are not explicitly listed in the provided datasheet. Designers should evaluate other LDOs from the same family, such as the LD6806F/xxH series, noting the difference in output impedance when disabled. Cross-vendor replacements must match the 1.2 V output, 200 mA current capability, SOT886 package dimensions, and electrical performance metrics.
