LD6806CX4/30P,315

Overview

The LD6806CX4/30P,315 is a low-dropout regulator (LDO) from the LD6806 series manufactured by NXP Semiconductors. It provides a fixed nominal output voltage of 3.0 V with an input voltage range of 2.3 V to 5.5 V. The device supports a maximum output current of 200 mA and features a typical dropout voltage of 60 mV at this rating. It utilizes a WLCSP4 wafer level chip-size package with a 0.4 mm pitch. Key electrical characteristics include a typical quiescent current of 70 µA in active mode and 1.0 µA in shutdown mode. The component includes integrated thermal protection, current limiting, and ESD protection rated at 10 kV Human Body Model.

Feature Summary

• Low-ohmic output state when disabled via integrated pull-down switching transistor
• Ultra-low noise performance with typical RMS output noise of 30 µV over 10 Hz to 100 kHz bandwidth
• Integrated temperature watchdog and current limiter for enhanced system reliability
• High power supply rejection ratio of 55 dB at 1 kHz frequency

Applications

• Analog and digital interfaces requiring lower than standard supply voltage in mobile appliances
• Mobile phone handsets and cordless telephones
• Personal digital devices and media players

Procurement Notes

Verify the specific suffix '315' against official NXP documentation to confirm reel packaging specifications. Confirm RoHS compliance status and dark green compliant material requirements as stated in the datasheet. Ensure the ordering information matches the exact type number LD6806CX4/30P for the correct low-ohmic output configuration.

Selection Notes

Select this component for applications requiring miniaturization due to its small WLCSP4 footprint. Ensure the load capacitance meets the minimum stability requirement of 0.7 µF with appropriate ESR. Verify that the input voltage remains within the 2.3 V to 5.5 V range and that the required output voltage is exactly 3.0 V.

Part Context

This part belongs to the LD6806 series of ultra low-dropout regulators designed for low-voltage applications. The series offers various output voltages and package options including WLCSP4, SOT886, and SOT753. The 'P' suffix indicates a low-ohmic output stage when disabled, distinguishing it from the 'H' variant which provides a high-ohmic state.

Replacement Considerations

LD6806CX4/30H: Identical electrical performance but provides a high-ohmic (3-state) output state when disabled instead of a low-ohmic state.
