Overview
The LD6806CX4/36H,315 is a fixed-output Low-DropOut regulator from NXP Semiconductors. It provides a nominal output voltage of 3.6 V with a maximum output current rating 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 full load. Packaged in a WLCSP4 wafer-level chip-size package with a 0.4 mm pitch, it includes integrated thermal protection, current limiting, and ESD protection rated at 10 kV Human Body Model.
Feature Summary
- Ultra-low dropout performance ensures high efficiency and minimized power consumption during operation.
- Low noise characteristics provide stable regulation for sensitive analog and digital interfaces.
- Integrated thermal watchdog and current limiter protect the device under fault conditions.
- High-ohmic (three-state) output state when disabled prevents loading on downstream circuits.
Applications
- Mobile phone handsets
- Cordless telephones
- Personal digital devices
Procurement Notes
Verify the specific suffix '315' against official documentation to confirm reel packaging specifications. Confirm that the 'H' designation corresponds to the high-ohmic output state required by the design. Ensure compatibility with lead-free reflow soldering profiles suitable for WLCSP packages.
Selection Notes
Select this component for applications requiring miniaturization due to its small WLCSP footprint. Choose this variant over 'P' versions if a high-impedance output state is necessary when the enable pin is low. Verify that the 3.6 V output aligns with the target circuit requirements.
Part Context
This part belongs to the LD6806 series of ultra-low-dropout regulators designed for portable electronics. The series offers various output voltages and package options, including WLCSP, SOT886, and SOT753. The CX4 suffix specifically denotes the wafer-level chip-size package configuration.
Replacement Considerations
LD6806CX4/36P,315: Provides identical electrical performance but features a low-ohmic output stage when disabled instead of a high-ohmic state.
FAQ
What is the output state of the LD6806CX4/36H when the device is disabled?
When disabled, the LD6806CX4/36H exhibits a high-ohmic (three-state) output state at the output pin.
Does the LD6806CX4/36H include internal protection mechanisms?
Yes, the device integrates a temperature watchdog for thermal protection and a current limiter for overload protection.
