Ultra low drop-low noise BiCMOS voltage regulators low ESR capacitors compatible

Operating RangeAutomotive
Operating Temp Min Celsius-40.0
Operating Temp Max Celsius125.0
ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2 (**)
GradeIndustrial
Package NameSOT23-5L

The LD3985 provides up to 150 mA, from 2.5 V to 6 V input voltage. The ultra low drop voltage, low quiescent current and low noise make it suitable for low power applications and in battery-powered systems. Regulator ground current increases slightly in dropout only, prolonging the battery life....
