and power dissipation P
according to the following formulas:

Dynamic supply current is higher due to the gate charge being delivered at the switching frequency. T he allowable operating frequency may be limited by power
dissipation at high input voltages.

T he ADP1148 version is tested with external feedback resistors, setting the nominal output voltage to 3.3 V.
