LT3030HFE#PBF Description
The LT3030HFE#PBF is a dual, micropower, low noise, low dropout linear regulator. The LT3030HFE#PBF operates with standard or independent input supplies for each channel, over a 1.7V to 20V input voltage range. Output 1/Output 2 supply 750mA/250mA respectively with a typical dropout voltage of 300mV. With an external 10nF bypass capacitor, output noise is only 20μVRMS over a 10Hz to 100kHz bandwidth. Designed for use in battery-powered systems, the low 120μA/75μA quiescent current makes it an ideal choice.
