0.80*V
ADJ
the PG pin goes to low impedance. If the device is functioning well, the Power
Good pin is at high impedance. If the output voltage is fixed using an external or internal
resistor divider, the Power Good threshold is 0.92*V
OUT
.
The use of the Power Good function requires an external pull-up resistor, which must be
connected between the PG pin and V
IN
or V
OUT
. The typical current capability of the PG pin
is up to 6 mA. The use of a pull-up resistor for PG in the range of 100 kΩ to 1 MΩ is
recommended. If the Power Good function is not used, the PG pin must remain floating.
