The power good reaction time
t
rr
is the time it takes the voltage regulator to set power
good output PG LOW after the output voltage has dropped below the power good
switching threshold. It is typically 0.5
μ
s for delay capacitor of 47 nF. For other values for
C
D
the reaction time can be estimated using the following equation:
t
rr
= 10 ns/nF

The Power Good output is an open collector output. It requires externally a pull up
resistor of at least 5 k
to Q.
