AQ112
7. Ultra low Dropout Operation
The AQ112 allows for ultra low dropout operation by connecting the pin
ENABLE
to >0.95V + Vout.
This results in a dropout of 100 mV at 150 mA of load current, between Vin and V
OUT
.
This feature is important when the supply voltage is dropping near the output regulated voltage.
Furthermore if the voltage dropout is low, the internal power dissipation is also reduced and the
thermal requirements of the device are less stringent.
