LD6805K/28H,115

Overview

The LD6805K/28H,115 is a fixed-output Low Dropout Regulator (LDO) from the NXP LD6805 series. It provides a nominal output voltage of 2.8 V with a maximum output current rating of 150 mA. The device operates within an input voltage range of 2.3 V to 5.5 V and features a dropout voltage of 250 mV at full load. It incorporates ultra-high Power Supply Rejection Ratio (PSRR) performance of 75 dB at 1 kHz and low quiescent current in shutdown mode. The component utilizes a DFN1010C-4 plastic package.

Feature Summary

Ultra-high PSRR capability for effective noise suppression
High-ohmic output state when disabled
Integrated over-current protection
Low quiescent current operation

Applications

Smart phones and mobile phone handsets
Digital still cameras
Portable media players
Personal navigation devices

Procurement Notes

Verify that the specific suffix '115' aligns with the manufacturer's standard packaging specifications for the LD6805K/28H variant. Confirm the high-ohmic output characteristic matches the design requirements, as opposed to the pull-down auto-discharge function found in 'P' suffix versions. Ensure compatibility with the required DFN1010C-4 footprint and thermal management strategies.

Selection Notes

Select this regulator for applications requiring precise 2.8 V supply rails with minimal voltage drop under load. The high PSRR makes it suitable for sensitive analog and digital interfaces in portable appliances. Consider the high-ohmic disabled state for power management schemes where floating outputs are preferred over active discharge. Evaluate PCB layout constraints due to the small DFN package size.

Part Context

This component belongs to the LD6805 series of low-dropout regulators designed for miniaturized portable electronics. The series offers various fixed output voltages ranging from 1.2 V to 3.6 V. The 'H' suffix denotes a high-ohmic output state in shutdown, distinguishing it from the 'P' suffix variants which feature an integrated pull-down transistor for auto-discharge functionality.
