LD6806F/29P,115

Overview

The LD6806F/29P,115 is a low-dropout regulator (LDO) from the LD6806 series manufactured by NXP Semiconductors. It provides a fixed nominal output voltage of 2.9 V with a maximum continuous 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 full load. It utilizes an SOT886 leadless plastic package and incorporates integrated thermal protection and overcurrent limiting circuits.

Feature Summary

• Ultra-low dropout performance ensures high efficiency and maximized power consumption reduction in mobile appliances.
• Low noise operation with minimal RMS output voltage ripple suitable for sensitive analog and digital interfaces.
• Integrated enable pin allows precise control of the regulator state, supporting active HIGH logic levels.
• Built-in safety mechanisms include thermal shutdown and current limiting to protect the device under fault conditions.

Applications

• Mobile phone handsets requiring component miniaturization
• Cordless telephones needing stable supply voltages
• Personal digital devices utilizing lower than standard supply rails

Procurement Notes

Verify the specific suffix '115' against official manufacturer documentation to confirm packaging details and compliance status. Ensure the selected variant matches the required low-ohmic output characteristic associated with the 'P' designation. Confirm that the SOT886 package dimensions align with the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require a compact LDO solution with a fixed 2.9 V output. The LD6806F/29P,115 is appropriate for applications demanding low quiescent current and high power supply rejection ratio. Designers must ensure the external load capacitance meets the minimum stability requirements specified in the datasheet to maintain proper regulator behavior across the operating temperature range.

Part Context

This part belongs to the LD6806 series of ultra low-dropout regulators designed for space-constrained portable electronics. The series offers multiple output voltage options and package types, including WLCSP4, SOT886, and SOT753. The 'F' designation indicates the SOT886 leadless plastic package, while the 'P' suffix denotes a low-ohmic output stage when disabled, distinguishing it from the high-ohmic 'H' variants.

Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Engineers should evaluate other LDOs from the LD6806 family or comparable low-noise regulators offering similar 2.9 V output and 200 mA current capability, ensuring compatibility with the SOT886 footprint and electrical specifications.
