Overview
The LD6806CX4/20P,315 is a fixed-output Low-DropOut regulator from NXP Semiconductors. It provides a nominal output voltage of 2.0 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. It utilizes a WLCSP4 package with a 0.4 mm pitch. The part 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
- Integrated temperature watchdog and overcurrent protection
- High power supply rejection ratio for effective ripple suppression
Applications
- Analog and digital interfaces requiring lower than standard supply voltage in mobile appliances
- Mobile phone handsets
- Cordless telephones
- Personal digital devices
Procurement Notes
Verify the specific suffix '315' against official documentation to confirm reel packaging specifications. Confirm that the 'P' designation indicates the low-ohmic output state required for your circuit design. Ensure compatibility with lead-free RoHS standards if applicable to your manufacturing process.
Selection Notes
Select this component for applications prioritizing miniaturization due to its small WLCSP footprint. Choose this variant over high-ohmic versions when a defined low-impedance state is necessary upon shutdown. Verify that the 2.0 V output aligns with the target load requirements and that the 200 mA current capability meets peak demand.
Part Context
This device belongs to the LD6806 series of ultra low-dropout regulators designed for portable electronics. The series offers various output voltages and package options, including WLCSP, SOT886, and SOT753. The CX4 suffix specifically denotes the wafer-level chip-size package configuration suitable for space-constrained designs.
Replacement Considerations
LD6806CX4/20H: Identical electrical characteristics but features a high-ohmic (3-state) output when disabled instead of a low-ohmic state.
