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 1. Line Regulation 3.05 3.10 3.15 3.20 3.25 3.30 3.35 3.0 3.5 4.0 VCC (V) 4.5 5mA Load 500mA Load 5.0 3.40 3.35 3.30 3.25 3.20 0 200 400 Load Current (mA) 600 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. Figure 3. Ground Current 80 100 60 40 20 0 0 200 400 Load Current (mA) 600 |
