Typical DC Characteristics
Unless stated otherwise, all DC characteristics were
measured at room temperature with a nominal VCC
supply voltage of 5V and an output capacitance of 10µF.
Resistive load conditions were used.
Line Regulation Characteristics of the regulator are
shown in Figure 1. At maximum rated load conditions
(500mA), a 100mV drop in regulation occurs when the
line voltage has collapses below 3.8V. For light load
conditions (5mA), regulation is maintained for line
voltages as low as 3.3V.
Load Regulation performance is shown from zero to
maximum rated load in Figure 2. A 10% to 100% change
of rated load, results in an output voltage change of less
than 10mV. This translates into an effective output
impedance of approximately 0.02Ω.

Figure 2. Load Regulation
Ground Current is shown across the entire range of
100
load conditions in Figure 3. The ground current increases
by 40µA across the range of load conditions. This
80
increase is due to the current limiting protective circuitry
becoming active.
