Typical DC Characteristics
Unless stated otherwise, all DC characteristics were measured at room temperature with a nominal VCC supply voltage of 5.0
volts and an output capacitance of 10µF.
Fig 1.1. VCC Line regulation
is measured while forcing the deselect threshold to an artificial
low level for loads of 100mA, 500mA and 1.5A. At the
maximum rated load of 1.5A, a drop in line regulation occurs
when the VCC supply voltage drops below 3.8V. For light
load conditions (100mA), regulation is maintained as low
as 3.2V.

Fig 1.2. VCC Load regulation (pulse condition)
performance is shown up to and beyond the rated load. A
change in load from 10% to 100% of rated current (150mA
to 1500mA) results in an output voltage change of about
20mV. This translates into an effective output impedance of
less than 15mΩ.

performance is shown up to and beyond the rated load. A
change in load from 10% to 100% of rated (50mA to 500mA)
results in an output voltage change of about 20mV. This
translates into an effective output impedance of less than
50mΩ.
