NR1641 Low Drop-Out (LDO) Voltage Regulators

Nisshinbo Micro Devices NR1641 Low Drop-Out (LDO) Voltage Regulators feature high ripple rejection, ultra-low output noise, high-speed response characteristics, and low quiescent current. The CMOS-based regulators implement MODE pin input voltage to select between the automatic alternative mode and the fixed fast mode. The automatic alternative mode changes the internal mode between the low power and fast modes according to the load current. Furthermore, the Slope of Output Voltage at start-up can be selected from 200μs/V or 500μs/V. By this option, the inrush current limit can be changed depending on the capacitance connected to the output pin.
