Overview
The LD6816CX4/20H,315 is a fixed-output Low Dropout (LDO) regulator providing a nominal voltage of 2.0 V with a maximum output current of 150 mA. It operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 45 mV at full load. The device incorporates over-temperature protection, output current limiting, and integrated ESD protection up to 10 kV HBM. It utilizes a WLCSP4 package measuring 0.76 mm x 0.76 mm with a 0.4 mm pitch.
Feature Summary
- Ultra-low dropout performance ensures high efficiency in portable applications
- High-ohmic three-state output when disabled for power conservation
- Low noise operation suitable for sensitive analog and digital interfaces
- Integrated thermal and current protection mechanisms
Applications
- Smart phones and mobile phone handsets
- Cordless telephones
- Digital still cameras
- Portable media players
Procurement Notes
Verify the specific suffix '315' against official NXP documentation to confirm reel packaging specifications. Ensure compatibility with the WLCSP4 footprint dimensions and soldering profiles defined in the datasheet. Confirm that the high-ohmic output state aligns with system requirements during shutdown phases.
Selection Notes
Select this component for designs requiring a compact form factor and low quiescent current. The 2.0 V fixed output is optimal for powering 1.8 V logic or RF sections from higher supply rails. Verify that the external capacitor meets the minimum capacitance and ESR requirements for stability across the operating temperature range.
Part Context
This part belongs to the LD6816 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series is designed for miniaturization in mobile appliances using monolithic silicon technology. The 'H' suffix specifically denotes the high-ohmic output configuration, distinguishing it from pull-down variants.
Replacement Considerations
LD6816CX4/20P: Offers identical electrical characteristics but includes an auto-discharge function via a pull-down transistor instead of a high-ohmic state.
