Automotive NR1640 200mA Ultra-low Noise Voltage Regulator

2022-02-26
The NR1640 is an ultra-low noise, high PSRR voltage regulator featuring 200 mA output current and 5.5 V maximum input voltage. With noise characteristics of 6μVrms and high ripple rejection of 80dB or more @100kHz, high quality power can be supplied, ideal for high precision sensing systems where noise is an issue. The slope of output voltage at startup can be selected from 4 types.
These options will meet the demand of suppression of inrush current and start-up slope requirement. In addition, the auto discharge function option will contribute to make the output shutdown fast to discharge output capacitance with internal discharge FET.
