Specifications (cont’d)
Note 1: Operating Characteristics are over Standard Operating Conditions unless otherwise specified.
Note 2: The hysteresis defines the maximum level of acceptable disturbance on V
CC
during switching. It is recommended that the
V
CC
source impedance be kept below 0.15Ω to ensure the switching disturbance remains below the hysteresis during select/
deselect transitions.
Note 3: Ground pin current consists of controller current (0.2mA) and regulator current when selected.

Typical DC Characteristics
Unless stated otherwise, all DC characteristics were
measured at room temperature with a nominal V
CC
supply voltage of 5.0 volts and an output capacitance
of 10
µF.
V
CC
Line Regulation, as shown in Figure 1, is mea-
sured while forcing the deselect threshold to an artifi-
cial low level for loads of 100mA, 500mA and 1.5A. At
the maximum rated load of 1.5A, a drop in line regula-
tion occurs when the V
CC
supply voltage drops below
3.8V. For light load conditions (100mA), regulation is
maintained as low as 3.2V.
Figure 1. V
CC
Line Regulation
V
CC
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 imped-
ance of less than 15MΩ.

Load Regulation (pulse condition) perfor-

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 imped-
ance of less than 50MΩ.

Typical DC Characteristics (cont’d)
Ground Current is shown across the entire range of
load conditions in Figure 4. The ground current of 2mA
has minimal variation across the range of load condi-
tions 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.
Figure 4. Ground Current
V
CC
Supply Current of the device is shown across the
entire V
CC
range in Figure 5.
In the absence of V
AUX
, the supply current remains
fixed at approximately 0.15mA until V
CC
reaches the
Select voltage threshold of 4.35V. At this point the reg-
ulator is enabled and a supply current of 1.0mA is con-
ducted.
When V
AUX
is present, the V
CC
supply current is less
than 10µA until V
CC
exceeds V
AUX
, at which point V
CC
then powers the controller (0.15mA). When V
CC
reaches V
SELECT
, the regulator is enabled.
