Typical DC Characteristics

Unless stated otherwise, all DC characteristics were

measured at room temperature with a nominal V

CC

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 0.02

Ω.

Figure 2. Load Regulation

Ground Current is shown across the entire range of

load conditions in Figure 3. The ground current increases

by 40µA across the range of load conditions. This

increase is due to the current limiting protective circuitry

becoming active.
