Overview
The LD6806CX4/22P,315 is a low-dropout regulator (LDO) from the LD6806 series manufactured by NXP Semiconductors. It provides a fixed nominal output voltage of 2.2 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. It utilizes a WLCSP4 package with a 0.4 mm pitch and dimensions of 0.76 mm x 0.76 mm. This variant includes a pull-down switching transistor for a low-ohmic output state when disabled.
Feature Summary
- Ultra-low dropout voltage design for high efficiency
- Low noise performance suitable for sensitive analog interfaces
- Integrated thermal protection and current limiting
- Low quiescent current in shutdown mode
Applications
- Mobile phone handsets
- Cordless telephones
- Personal digital devices
- Media players
Procurement Notes
Verify the specific suffix '315' against official documentation to confirm reel packaging specifications. Ensure compatibility with WLCSP4 soldering profiles as wave soldering is unsuitable. Confirm RoHS compliance status through manufacturer datasheets before integration into production lines.
Selection Notes
Select this component for applications requiring miniaturization due to its small WLCSP4 footprint. Choose this variant over high-ohmic types if a defined low-impedance state is required during disable periods. Ensure external capacitors meet minimum ESR 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 packages including SOT886 and SOT753. The 'P' suffix indicates the presence of a pull-down transistor, distinguishing it from 'H' variants which feature a high-ohmic output state.

FAQ
What is the output state of the LD6806CX4/22P when disabled?
The LD6806CX4/22P contains a pull-down switching transistor that provides a low-ohmic output stage when the device is disabled.
Is wave soldering suitable for the WLCSP4 package?
No, wave soldering is not suitable for WLCSP packages; reflow soldering must be used.
