Overview
The LD6806CX4/36P,315 is a fixed-output Low-DropOut regulator from NXP Semiconductors. It provides a nominal output voltage of 3.6 V with a maximum continuous output current of 200 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 60 mV at the rated load. It utilizes a WLCSP4 package with a 0.4 mm pitch. Key electrical characteristics include a typical quiescent current of 70 µA in active mode and 1.0 µA in shutdown mode. The regulator offers low noise performance with a typical RMS output noise of 30 µV over a 10 Hz to 100 kHz bandwidth.
Feature Summary
- Ultra-low dropout voltage capability for maximizing efficiency in battery-powered applications
- Low noise output suitable for sensitive analog and digital interfaces
- Integrated thermal protection and current limiting for enhanced reliability
- Low-ohmic pull-down transistor in disabled state for rapid output discharge
Applications
- Mobile phone handsets requiring component miniaturization
- Cordless telephones
- Personal digital devices
- Media players
Procurement Notes
Verify the specific suffix '315' against official documentation to confirm reel packaging details. Confirm RoHS compliance status as indicated in the datasheet. Ensure the low-ohmic output variant ('P') matches system requirements for disabled states. Validate that the 3.6 V fixed output aligns with target circuit design specifications before procurement.
Selection Notes
Select this component when a compact form factor is required alongside stable 3.6 V regulation. The WLCSP4 package supports high-density PCB layouts. Consider the 200 mA current limit for load requirements. The low quiescent current aids in extending battery life. Verify external capacitor ESR requirements for stability during operation.
Part Context
This part belongs to the LD6806 series of ultra-low-dropout regulators designed for mobile appliances. The series includes variants with different output voltages and packages, such as SOT886 and SOT753. The CX4 designation specifically refers to the Wafer Level Chip-Scale Package format, distinguishing it from leaded or larger surface-mount options within the same functional family.
Replacement Considerations
LD6806CX4/36H: Identical electrical performance but features a high-ohmic (3-state) output when disabled instead of the low-ohmic pull-down found in the 'P' variant.
