TLE 4290
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 µs 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 × C_D
The Power Good output is an open collector output. It requires externally a pull up
resistor of at least 5 kΩ to Q.
