Overview
The LD6806CX4/12P,315 is a fixed-output Low-DropOut regulator from the NXP LD6806 series. It provides a nominal output voltage of 1.2 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 x 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 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 footprint supports component miniaturization in space-constrained designs.
Applications
- Mobile phone handsets
- Cordless telephones
- Personal digital devices
Procurement Notes
Verify the specific suffix '315' against official documentation to confirm reel packaging specifications. Confirm RoHS compliance status and dark green material requirements prior to procurement. Ensure the selected variant matches the required low-ohmic output behavior for the application design.
Selection Notes
Select this component for applications requiring precise 1.2 V regulation with minimal voltage drop. Consider the WLCSP4 package dimensions for PCB layout constraints. Verify that the external load capacitance meets the minimum stability requirement of 0.7 µF. Evaluate thermal dissipation capabilities based on the expected ambient temperature and board copper area.
