TYPICAL DC CHARACTERISTICS
Unless stated otherwise, all DC characteristics were
measured at room temperature with a nominal VCC supply
voltage of 5.0 V and an output capacitance of 10 mF.
VCC Line Regulation, as shown in V, is measured while
forcing the deselect threshold to an artificial low level for
loads of 100 mA, 500 mA and 1.5 A. At the maximum rated
load of 1.5 A, a drop in line regulation occurs when the VCC
supply voltage drops below 3.8 V. For light load conditions
(100 mA), regulation is maintained as low as 3.2 V
VSBY Load Regulation (pulse condition) performance
is shown up to and beyond the rated load. A change in load
from 10% to 100% of rated (50 mA to 500 mA) results in an
output voltage change of about 20 mV. This translates into
an effective output impedance of less than 50 MW.

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 (150 mA to 1500 mA)
results in an output voltage change of about 20 mV. This
translates into an effective output impedance of less than
15 MW.
Figure 3. VSBY Load Regulation
Ground Current is shown across the entire range of load
conditions in Ground Current. The ground current of 2 mA
has minimal variation across the range of load conditions
and shows only a slight increase at maximum load. This
slight increase at rated load is due to the current limit
protection circuitry becoming active.
