Overview
The LD6806CX4/33P,315 is a low-dropout regulator (LDO) from NXP Semiconductors. It provides a fixed nominal output voltage of 3.3 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. Key electrical characteristics include a typical quiescent current of 70 µA, an RMS output noise voltage of 30 µV over the 10 Hz to 100 kHz bandwidth, and a power supply rejection ratio of 55 dB at 1 kHz. The part includes integrated thermal protection and current limiting.
Feature Summary
- Ultra-low dropout voltage design for high efficiency
- Low noise performance suitable for sensitive analog circuits
- Integrated enable pin for active HIGH control
- Low-ohmic output state when disabled
Applications
- Mobile phone handsets
- Cordless telephones
- Personal digital devices
- Media players
Procurement Notes
Verify the specific suffix '315' against official documentation to confirm tape-and-reel specifications or variant details. Confirm RoHS compliance status as per the datasheet revision. Ensure the ordering code matches the exact package type and output voltage requirements for your design.
Selection Notes
Select this component for applications requiring miniaturization due to its small WLCSP4 footprint. Choose this part if a fixed 3.3 V output is needed with low noise characteristics. Consider the low-ohmic shutdown feature if system isolation is required during inactive states.
Part Context
This component belongs to the LD6806 series of ultra low-dropout regulators. The series offers various output voltages and packages, including WLCSP4, SOT886, and SOT753. The 'P' suffix indicates a low-ohmic output stage when disabled, distinguishing it from the 'H' variant which provides a high-ohmic state.
Replacement Considerations
Consult official NXP documentation for direct substitutes. Verify compatibility regarding output voltage, package dimensions, and electrical characteristics before replacement.
