LDS3985M33R

Very low drop and low noise BiCMOS 300 mA voltage regulator

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 LDS3985 provides up to 300 mA, from 2.5 V to 6 V input voltage. It is stable with ceramic and high quality tantalum capacitor. The ultra low drop voltage, low quiescent current and low noise make it suitable for low power applications and battery-powered systems. Shutdown logic control function...
