LD6806CX4/30H,315

Overview

The LD6806CX4/30H,315 is a fixed-output Low-DropOut regulator from the LD6806 series. It provides a nominal output voltage of 3.0 V with an input range of 2.3 V to 5.5 V and a maximum output current of 200 mA. The device features ultra-low dropout characteristics, typically 60 mV at full load. It incorporates integrated thermal protection, current limiting, and high-ohmic (three-state) output behavior when disabled. The component utilizes a WLCSP4 package with a 0.4 mm pitch.

Feature Summary

• Ultra low-dropout performance for maximizing efficiency
• Low noise operation suitable for sensitive analog circuits
• Integrated thermal shutdown and overcurrent protection
• High-ohmic output state in shutdown mode

Applications

• Mobile phone handsets
• Cordless telephones
• Personal digital devices
• Media players

Procurement Notes

Verify the specific suffix '315' against official NXP documentation to confirm reel specifications or tape-and-reel details. Ensure the ordering code matches the exact WLCSP4 package variant required for your board layout. Confirm RoHS compliance status through the manufacturer's latest datasheet revision.

Selection Notes

Select this part for applications requiring a compact footprint and stable 3.0 V supply. The high-ohmic output feature is critical if the downstream circuit requires isolation during system sleep modes. Verify that the external capacitor meets the minimum ESR requirements for stability.

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 SOT886 and SOT753. The CX4 designation specifically indicates the Wafer Level Chip Size Package format.

Replacement Considerations

LD6806CX4/30P offers a similar form factor but provides a low-ohmic output stage instead of high-ohmic.
