Device Overview

Summary

LX8240 is a low-dropout regulator offering the highest Power Supply Rejection Ratio (PSRR), higher than 48 dB over all frequency up to 100kHz, and higher than 32 dB over all frequency up to 1MHz for LDO devices supplying 800mA of output current. LX8240 also requires very low quiescent current. It has separate Bias and Input supply rails to improve efficiency and minimize power dissipation. The VBIAS input includes a voltage compliance range from 2.7V to 5.5V, and the VIN supply range is 1.2V to 4.2V. The output voltage is programmed by an external resistor divider utilizing the 0.5V reference feedback (FB) pin allowing output voltages as low as 1V. LX8240 is an ideal selection for battery-powered systems where the low quiescent current cannot be compromised. It is also guaranteed to be the stable even with only a 1µF ceramic capacitor. To protect the device the LX8240 also includes internal thermal shutdown, and overcurrent limit features.
