Overview
The LD6816CX4/20P,315 is a fixed-output Low DropOut regulator from NXP Semiconductors. It provides a nominal output voltage of 2.0 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 incorporates an integrated pull-down switching transistor for auto discharge functionality when disabled. The component utilizes a WLCSP4 package with a 0.4 mm pitch.
Feature Summary
- Ultra-low dropout performance ensuring high efficiency in portable applications
- Integrated pull-down transistor providing low-ohmic output state during shutdown
- Low quiescent current operation extending battery life in mobile devices
- Built-in over-temperature protection and output current limiting
Applications
- Analog and digital interfaces requiring lower than standard supply voltages in mobile appliances
- Smart phones and mobile phone handsets
- Digital still cameras and 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 exact pull-down variant required for your circuit design.
Selection Notes
Select this component for designs prioritizing miniaturization due to its small WLCSP footprint. Ensure the application requires a fixed 2.0 V output. Verify that the external load capacitance meets the minimum stability requirements specified in the electrical characteristics section.
Part Context
This part belongs to the LD6816 series of ultra-low dropout regulators manufactured by NXP Semiconductors. The series is designed for monolithic silicon technology and offers various fixed output voltages between 1.2 V and 3.6 V. The 'P' suffix indicates the inclusion of an auto-discharge function via a pull-down transistor.
Replacement Considerations
LD6816CX4/20H serves as a functional substitute if a high-ohmic (3-state) output is acceptable instead of the auto-discharge feature.
