LD6805K/30P,115

Overview

The LD6805K/30P,115 is a fixed-output Low Dropout regulator (LDO) from the NXP LD6805 series. It provides a nominal output voltage of 3.0 V with a maximum load current rating of 150 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a typical dropout voltage of 250 mV at full load. It incorporates an auto discharge function via a pull-down switching transistor in disabled mode. Key electrical characteristics include a Power Supply Rejection Ratio (PSRR) of 75 dB at 1 kHz and low quiescent current of 0.1 µA in shutdown.

Feature Summary

Integrates an auto discharge function using a pull-down switching transistor to provide a low-ohmic output state when disabled.
Delivers high power supply rejection ratio (PSRR) of 75 dB at 1 kHz for effective noise suppression.
Features ultra-low quiescent current consumption in shutdown mode to extend battery life.
Includes integrated electrostatic discharge (ESD) protection up to 6 kV Human Body Model.

Applications

Powering analog and digital interfaces requiring lower than standard supply voltages in mobile appliances.
Supplying portable devices such as smart phones, mobile phone handsets, and cordless telephones.
Providing regulated power for digital still cameras, mobile internet devices, and personal navigation devices.

Procurement Notes

Verify that the specific suffix '115' corresponds to the standard DFN1010C-4 (SOT1194-1) package configuration documented in the official datasheet. Confirm the nominal output voltage matches the required 3.0 V specification for the target application circuit design.

Selection Notes

Select this component when a compact LDO with an active pull-down feature is required for rapid output discharge 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 the 150 mA rating for stable operation.

Part Context

This part belongs to the LD6805 series of low-dropout regulators manufactured by NXP Semiconductors. The series is designed for portable applications requiring miniaturization, utilizing a monolithic silicon technology housed in a 1x1 mm plastic DFN package. The 'P' suffix specifically denotes the variant equipped with the auto discharge functionality.
