Overview
The LD6806CX4/28H,315 is a fixed-output Low-DropOut regulator from NXP Semiconductors. It provides a nominal output voltage of 2.8 V with an input 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 (0.76 mm x 0.76 mm), it includes thermal protection, current limiting, and integrated ESD protection.
Feature Summary
- Ultra-low dropout performance for high efficiency
- Low noise operation suitable for sensitive analog circuits
- High-ohmic output state when disabled
- Integrated thermal and overcurrent protection
Applications
- Mobile phone handsets
- Cordless telephones
- Personal digital devices
- Media players
Procurement Notes
Verify the specific suffix '315' against official documentation to confirm reel specifications or tape-and-reel details. Confirm RoHS compliance status and lead-free manufacturing claims directly with the manufacturer. Ensure the high-ohmic output characteristic aligns with system requirements during shutdown.
Selection Notes
Select this component for applications requiring miniaturization due to its small WLCSP footprint. Ensure the required output voltage matches the fixed 2.8 V specification. Verify that the input voltage remains within the 2.3 V to 5.5 V operating range under all conditions.
Part Context
This part belongs to the LD6806 series of ultra low-dropout regulators designed for mobile appliances. The series offers various fixed output voltages and package options including WLCSP, SOT886, and SOT753. The CX4 variant specifically denotes the wafer-level chip-size package optimized for space-constrained designs.
