The NR1640 is a CMOS-based ultra-low noise, high
PSRR voltage regulator featuring 200 mA output current
and 5.5 V maximum input voltage.
With noise characteristics of 6 μVrms and high ripple
rejection of 80 dB or more @100 kHz, 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.
