Achieving the highest level of low noise, high PSRR, low current consumption, and high-speed response performance.
The "NR1641" series is an LDO voltage regulator that boasts the world's highest level of low output noise: 3.7μVrms and ripple rejection rate: 80dB (f=10kHz) for products that do not require noise-reducing capacitors. It also features a built-in "soft start function" that controls the slope at startup. This function is expected to help suppress inrush current and facilitate control when there are constraints on the power input of subsequent devices. Furthermore, it supports an output current of 1A and, by utilizing the built-in low power consumption/high-speed mode automatic switching function, it achieves both low self-consumption current and high responsiveness. *As of April 2023, according to Nisshinbo Micro Devices.
