LD6806F/13P,115

Overview

The LD6806F/13P,115 is a low-dropout regulator (LDO) from NXP Semiconductors featuring a fixed 1.3 V output voltage and a 200 mA current rating. It operates within an input voltage range of 2.3 V to 5.5 V and utilizes the SOT886 leadless plastic package. The device incorporates a pull-down switching transistor that ensures a low-ohmic output state when disabled. Key electrical characteristics include a typical dropout voltage of 60 mV at full load, a quiescent current of 70 µA, and an RMS output noise of 30 µV across the 10 Hz to 100 kHz bandwidth.

Feature Summary

• Ultra-low dropout performance with minimal voltage loss under high load conditions
• Low-noise operation suitable for sensitive analog and digital interfaces
• Integrated thermal protection and overcurrent limiting for enhanced reliability
• Active pull-down mechanism provides a defined low-impedance state during shutdown

Applications

• Mobile phone handsets requiring component miniaturization
• Cordless telephones with strict space constraints
• Personal digital devices needing stable low-voltage power supplies

Procurement Notes

Verify the specific suffix '115' against official ordering documentation to confirm tape-and-reel specifications or marking details. Ensure compatibility with RoHS and Halogen-free manufacturing standards required by your assembly process. Confirm that the SOT886 footprint matches your PCB design guidelines before finalizing procurement orders.

Selection Notes

Select this component when a fixed 1.3 V rail is required in compact mobile designs. The SOT886 package offers a small form factor ideal for space-constrained layouts. Consider the low-ohmic output feature if system-level discharge of downstream capacitance is necessary upon disablement. Verify that the external capacitor ESR remains within the specified stability range.

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 package options such as WLCSP4 and SOT753. The 'F' designation indicates the SOT886 package type, while the 'P' suffix denotes the low-ohmic output configuration with an integrated pull-down transistor.

Replacement Considerations

Direct pin-compatible replacements are not explicitly listed in the provided datasheet. Designers should evaluate other LDOs from the LD6806 family or comparable low-noise regulators ensuring matching output voltage, current capacity, and package dimensions.
