Overview
The LD6816CX4/14P,315 is a fixed-output Low DropOut regulator from NXP Semiconductors. It provides a nominal output voltage of 1.4 V with a maximum output current rating of 150 mA. The device 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. It utilizes a WLCSP4 package with dimensions of 0.76 mm x 0.76 mm and a 0.4 mm pitch. The part includes an integrated pull-down switching transistor for auto discharge functionality.
Feature Summary
- Ultra-low dropout performance ensuring high efficiency in portable applications
- Integrated auto discharge function via pull-down transistor when disabled
- Low noise operation suitable for sensitive analog and digital interfaces
- Built-in over-temperature protection and output current limiting
Applications
- Smart phones and mobile phone handsets
- Digital still cameras
- Portable media players
- Personal navigation devices
Procurement Notes
Verify the specific suffix '315' against official documentation to confirm reel packaging specifications. Confirm RoHS compliance status as detailed in the manufacturer's datasheet. Ensure the ordering code matches the required 1.4 V fixed output variant within the LD6816 series.
Selection Notes
Select this component for designs requiring miniaturization due to its WLCSP4 footprint. Choose the 'P' suffix version specifically when an active low-ohmic output state is needed during shutdown. Ensure external capacitors meet the minimum ESR requirements for stability.
Part Context
This device belongs to the LD6816 series of ultra-low dropout regulators designed for space-constrained environments. The series offers various fixed output voltages between 1.2 V and 3.6 V. The 'P' designation indicates the inclusion of an auto-discharge feature, distinguishing it from the 'H' variant which presents a high-ohmic state when disabled.
Replacement Considerations
LD6816CX4/14H: Identical electrical characteristics but lacks the auto-discharge pull-down transistor.
