NR1641 series 1A Equipped with Low Power Mode Ultra-Low Noise Low Dropout Voltage Regulator

PublishTime：2024-06-27

●Achieves low quiescent current, ultra-low noise, and high ripple rejection without the need for noise reduction capacitors.
●The slope of output voltage at start-up can be selected from 200 μs/V or 500 μs/V, making it easy to deal with inrush current.
●Selectable from 3 types of packages (ultra small size/high wattage/good balance)
