Overview
The LD6816CX4/27H,315 is a fixed-output Low DropOut regulator from NXP Semiconductors with a nominal output voltage of 2.7 V. It operates within an input voltage range of 2.3 V to 5.5 V and provides a maximum output current of 150 mA. The device features a typical dropout voltage of 45 mV at full load and maintains a low quiescent current of 0.1 µA in shutdown mode. It incorporates over-temperature protection, output current limiting, and integrated ESD protection up to 10 kV HBM. The component utilizes a WLCSP package with a 0.4 mm pitch.
Feature Summary
- Ultra-low dropout performance ensuring high efficiency during operation
- Low noise characteristics suitable for sensitive analog and digital interfaces
- High-ohmic (three-state) output state when disabled
Applications
- Smart phones and mobile phone handsets
- Digital still cameras
- Portable media players
Procurement Notes
Verify the specific suffix '315' against official manufacturer documentation to confirm reel packaging specifications. Ensure compatibility with RoHS compliance standards and lead-free manufacturing processes required for your assembly line. Confirm that the high-ohmic output configuration aligns with your system's power management requirements.
Selection Notes
Select this component for applications requiring precise 2.7 V regulation in space-constrained designs. The WLCSP package facilitates miniaturization for portable devices. Consider the 150 mA current rating and ultra-low dropout voltage for battery-powered systems where maximizing efficiency is critical.
Part Context
This part belongs to the LD6816 series of ultra-low dropout regulators designed for portable appliances. The series offers various fixed output voltages between 1.2 V and 3.6 V. The 'H' suffix indicates a high-ohmic output state upon disable, distinguishing it from pull-down variants.
