The reset reaction time
t
rr
is the time it takes the voltage regulator to set the reset out
LOW after the output voltage has dropped below the reset threshold. It is typically 1
μ
s
for delay capacitor of 47 nF. For other values for
C
d
the reaction time can be estimated
using the following equation:
