Overview
The LD6806CX4/14P,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 operating input voltage range of 2.3 V to 5.5 V. The device supports a continuous output current of 200 mA and features a typical dropout voltage of 60 mV at full load. Packaged in a WLCSP4 wafer-level chip-size package with a 0.4 mm pitch, it includes integrated thermal protection, current limiting, and ESD protection rated at 10 kV Human Body Model.
Feature Summary
- Ultra-low dropout performance ensures high efficiency and minimized power consumption during operation.
- Low noise characteristics provide stable regulation for sensitive analog and digital interfaces.
- Integrated pull-down switching transistor creates a low-ohmic output state when disabled.
- Compact WLCSP4 package design facilitates component miniaturization in space-constrained applications.
Applications
- Mobile phone handsets
- Cordless telephones
- Personal digital devices
Procurement Notes
Verify the specific suffix '315' against official documentation to confirm reel packaging specifications. Ensure compatibility with lead-free RoHS standards and dark green compliance requirements. Confirm that the WLCSP4 package dimensions align with the target PCB footprint and soldering profile constraints.
Selection Notes
Select this variant for designs requiring a precise 1.4 V rail within the LD6806 family. Consider the low-ohmic shutdown behavior if active discharge of the output capacitor is required. Evaluate the thermal resistance characteristics relative to the PCB layout to ensure junction temperature limits are not exceeded under maximum load conditions.
Part Context
This component belongs to the LD6806 series of ultra-low-dropout regulators manufactured by NXP Semiconductors. The series utilizes monolithic silicon technology and offers various output voltages ranging from 1.2 V to 3.6 V. It is designed for portable appliances where battery lifetime and operating stability are critical priorities.
