LD6806CX4/14H,315

Overview

The LD6806CX4/14H,315 is a fixed-output Low-DropOut regulator from the NXP LD6806 series. It provides a nominal output voltage of 1.4 V with an input voltage range of 2.3 V to 5.5 V. The device supports up to 200 mA continuous output current and features a typical dropout voltage of 60 mV at full load. Packaged in a WLCSP4 wafer level chip-size package (0.76 mm x 0.76 mm), it offers low quiescent current, high PSRR, and integrated thermal and overcurrent protection.

Feature Summary

• Ultra-low dropout performance for maximizing efficiency
• Low noise operation suitable for sensitive analog interfaces
• High-ohmic (three-state) output when disabled
• Integrated thermal shutdown and current limiting

Applications

• Mobile phone handsets
• Cordless telephones
• Personal digital devices
• Media players requiring lower than standard supply voltages

Procurement Notes

Verify the specific suffix '315' against official documentation to confirm reel packaging details. Confirm RoHS compliance status and dark green material specifications. Ensure the high-ohmic output characteristic aligns with system requirements during disable states. Validate component authenticity through authorized distribution channels.

Selection Notes

Select this variant for applications requiring a precise 1.4 V rail in compact designs. The WLCSP4 package minimizes board space compared to leaded options. Consider the high-ohmic output state if bus isolation is needed when the regulator is inactive. Verify external capacitor ESR requirements for stability across the operating temperature range.

Part Context

This component 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 packages, such as SOT886 and SOT753. The 'H' suffix denotes a high-ohmic output state upon disabling, distinguishing it from 'P' variants which feature a pull-down transistor.
