Overview
The LD6806CX4/16H,315 is a low-dropout regulator (LDO) from the LD6806 series manufactured by NXP Semiconductors. It provides a fixed nominal output voltage of 1.6 V with an input voltage range of 2.3 V to 5.5 V. The device supports a continuous output current of 200 mA and features ultra-low dropout characteristics, typically 60 mV at full load. It utilizes a WLCSP4 package with a 0.4 mm pitch. Key electrical specifications include a typical quiescent current of 70 µA, shutdown current of 1.0 µA, and RMS output noise of 30 µV over a 10 Hz to 100 kHz bandwidth.
Feature Summary
- Ultra-low dropout voltage ensures high efficiency and minimal power consumption during operation.
- Low noise performance suitable for sensitive analog and digital interface applications.
- Integrated thermal protection and current limiter safeguard against overload conditions.
- High-ohmic 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 details. Confirm RoHS compliance status as indicated in the datasheet. Ensure compatibility with lead-free reflow soldering profiles specified for WLCSP packages. Check availability through authorized distributors as supply status may vary.
Selection Notes
Select this component for designs requiring miniaturization due to its small WLCSP footprint. Consider the 1.6 V fixed output for powering logic or analog sections needing that specific rail. Evaluate the need for the high-ohmic disabled state versus the low-ohmic variant if system isolation is required. Verify external capacitor requirements for stability.
Part Context
This part belongs to the LD6806 series of ultra low-dropout regulators designed for mobile appliances. The series offers various output voltages and package options including WLCSP, SOT886, and SOT753. The 'H' suffix denotes a high-ohmic output state when disabled, distinguishing it from the 'P' variant which features a pull-down transistor.
Replacement Considerations
Consult official substitution lists for equivalent LDOs with similar voltage and current ratings. Verify pinout compatibility if replacing with other packages like SOT886 or SOT753. Ensure thermal management requirements are met by alternative components.
