The power good reaction time

t

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

t

The Power Good output is an open collector output. It requires externally a pull up

resistor of at least 5 k

Ω to Q.
