Overview
The LD6816CX4/C13P,315 is a linear voltage regulator IC from the LD6816 series, manufactured by Nexperia USA Inc. It provides a fixed positive output voltage of 1.3V with a maximum load current capability of 150mA. The device utilizes a compact 4-WLCSP package measuring 0.76x0.76 mm. As a Low Dropout (LDO) regulator, it features a typical voltage drop of 45 mV at full load, ensuring efficient power regulation in space-constrained applications.
Feature Summary
- Compact 4-WLCSP package for minimal board space utilization
- Fixed positive output voltage regulation
- Low dropout performance for high efficiency
Applications
- Portable electronic devices requiring small form factors
- Battery-powered systems needing efficient voltage regulation
- Embedded circuits with strict space constraints
Procurement Notes
Verify the specific output voltage suffix matches the design requirement of 1.3V. Confirm the package type is 4-WLCSP and the tape/reel quantity corresponds to project needs. Ensure compatibility with the target PCB footprint and soldering profile for WLCSP components.
Selection Notes
Select this component when a fixed 1.3V output is required in a very small footprint. Consider the 150mA current limit and low dropout characteristics for battery-operated applications. Compare against other LDOs if higher current or adjustable voltage is needed.
Part Context
Part of the LD6816 family of small-size Low Dropout regulators. The series offers various fixed output voltages and shares common packaging and electrical characteristics, designed for miniaturized consumer electronics and portable devices.
Replacement Considerations
Check for direct pin-compatible alternatives within the LD6816 series with different voltage outputs. Verify equivalent LDOs with similar current ratings and package dimensions if sourcing issues arise.
