Overview
The LD6806CX4/28P,315 is a fixed-output Low-DropOut regulator from NXP Semiconductors. It provides a nominal output voltage of 2.8 V with a maximum output current rating of 200 mA. The device 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. Packaged in a WLCSP4 wafer-level chip-size package measuring 0.76 mm by 0.76 mm, it includes integrated thermal protection, current limiting, and ESD protection rated at 10 kV Human Body Model.
Feature Summary
- Ultra-low dropout voltage ensures high efficiency and minimized power consumption during operation.
- Low noise performance supports sensitive analog and digital interfaces requiring clean supply voltages.
- Integrated pull-down switching transistor provides a low-ohmic output state when the device is disabled.
- Compact WLCSP4 package design facilitates component miniaturization for space-constrained portable applications.
Applications
- Mobile phone handsets
- Cordless telephones
- Personal digital devices
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Confirm RoHS compliance status and environmental declarations prior to integration. Ensure application circuits meet minimum external capacitance requirements for stability. Validate that input voltage levels remain within the specified operating limits to prevent damage.
Selection Notes
Select this component for designs requiring a fixed 2.8 V rail with minimal footprint. Consider the low quiescent current in shutdown mode for battery-powered systems. Evaluate the thermal resistance characteristics relative to the PCB layout to ensure junction temperatures remain within safe operating limits under maximum load conditions.
