Ultra-Low Noise Voltage Regulator with High PSRR for In-Vehicle Camera System and High Precision Sensing System
Nisshinbo Micro Devices Inc. has launched an ultra-low noise, high PSRR voltage regulator NR1640 that features 200 mA output current and 5.5 V maximum input voltage. This new regulator with noise characteristics of 6 μVrms and high ripple rejection of 80 dB or more is ideal for high precision sensing systems and in-vehicle camera systems. Moreover, it features an auto discharge function option that will contribute to make the output shutdown fast to discharge output capacitance with internal discharge FET.
