LD6806F/30P,115

Overview

The LD6806F/30P,115 is a low-dropout regulator (LDO) from the NXP LD6806 series. It provides a fixed nominal output voltage of 3.0 V with a maximum continuous output current rating of 200 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and maintains a typical dropout voltage of 60 mV at full load. It features ultra-low noise performance with a typical RMS output noise of 30 µV across the 10 Hz to 100 kHz bandwidth. The component is housed in a compact SOT886 leadless plastic package.

Feature Summary

• Provides a low-ohmic pull-down state on the output pin when disabled, ensuring rapid discharge of external capacitance.
• Integrates comprehensive protection mechanisms including thermal shutdown, overcurrent limiting, and integrated ESD protection rated at 10 kV Human Body Model.
• Delivers high power supply rejection ratio (PSRR) to effectively suppress input voltage ripples and noise.
• Utilizes monolithic silicon technology for superior operating stability and miniaturization.

Applications

• Analog and digital interfaces requiring lower than standard supply voltages in mobile appliances
• Mobile phone handsets and personal digital devices requiring component miniaturization
• Cordless telephones and media players

Procurement Notes

Verify that the specific ordering suffix ',115' corresponds to the required tape-and-reel packaging configuration as defined by NXP Semiconductors. Confirm that the SOT886 package variant matches the design footprint requirements. Ensure compliance with RoHS3 standards and dark green compliant material specifications (free of Halogen and Antimony) for the target application environment.

Selection Notes

Select this component when a fixed 3.0 V rail is required with minimal board space constraints. The SOT886 package offers a small footprint suitable for dense layouts. Consider the low-ohmic output feature if fast discharge times are necessary upon shutdown. Ensure the application input voltage remains within the 2.3 V to 5.5 V range and that the load current does not exceed 200 mA continuously.

Part Context

This part belongs to the LD6806 series of ultra low-dropout regulators designed for mobile applications. The series includes variants with different output voltages and package types, such as WLCSP4 and SOT753. The 'F' designation indicates the SOT886 leadless plastic package, while the '30' specifies the 3.0 V nominal output voltage. The 'P' suffix denotes the low-ohmic output stage behavior when the device is disabled.

FAQ

What is the output state of the LD6806F/30P when the enable pin is low?

When the enable pin is low, the LD6806F/30P enters a low-ohmic output state due to its internal pull-down switching transistor, actively pulling the output voltage down rather than leaving it in a high-impedance state.

How does the LD6806F/30P handle overcurrent conditions?

The device incorporates an integrated current limiter that protects the regulator and external components against short-circuit conditions and excessive load currents.
