LD6806F/23H,115

Overview

The LD6806F/23H,115 is a low-dropout regulator (LDO) from NXP Semiconductors providing a fixed 2.3 V output with a maximum current rating of 200 mA. It 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. The device utilizes the SOT886 leadless plastic package and incorporates high-ohmic output state characteristics when disabled. Key electrical specifications include a typical quiescent current of 1.0 µA in shutdown mode, 30 µV RMS output noise over a 10 Hz to 100 kHz bandwidth, and a power supply rejection ratio of 55 dB at 1 kHz.

Feature Summary

• Ultra-low dropout voltage performance ensuring efficient power conversion under varying load conditions
• Integrated thermal protection and current limiting mechanisms for enhanced operational safety
• High-ohmic output state configuration when disabled to minimize leakage in multi-rail systems
• Low noise output suitable for sensitive analog and digital interface applications

Applications

• Mobile phone handsets requiring component miniaturization
• Cordless telephones with strict space constraints
• Personal digital devices needing stable low-voltage supplies
• Media players and portable appliances

Procurement Notes

Verify that the ordering suffix matches the required package type and output voltage variant. Confirm RoHS compliance and halogen-free status requirements against specific project standards. Ensure external capacitor selection meets the minimum capacitance and ESR specifications for stability. Check for any specific moisture sensitivity level handling instructions during assembly.

Selection Notes

Select this component for designs prioritizing small footprint and low quiescent current consumption. The SOT886 package offers a compact solution for dense PCB layouts. Consider the high-ohmic output feature if system isolation during shutdown is critical. Validate that the input voltage range accommodates the battery or supply rail variations expected in the target application environment.

Part Context

This part belongs to the LD6806 series of ultra-low-dropout regulators designed for mobile and portable electronics. The series includes variants with different output voltages and package options such as WLCSP4 and SOT753. The LD6806F/23H specifically denotes the SOT886 package version with a fixed 2.3 V output and high-ohmic disable state, manufactured using monolithic silicon technology.

Replacement Considerations

Direct substitutes within the same family include other LD6806 variants with different output voltages but identical packages, such as LD6806F/25H or LD6806F/33H. Cross-family replacements require verification of pin compatibility, output voltage accuracy, and package dimensions.
