6.6 Typical Characteristics

At VOnom = 3.3 V, VI = VOnom + 0.5 V or 2.2 V (whichever is greater), IO = 100 mA, V(EN) = VI, C(IN) = 1 μF, C(OUT) = 4.7 μF, and C(NR) = 0.01

μF; all temperature values refer to TJ, unless otherwise noted.

NOTE: The Y-axis shows 1% VO per division

Figure 1. Load Regulation

Figure 2. Load Regulation Under Light Loads

VO = 0.8 V

IO = 750 mA

VO = 0.8 V

IO = 5 mA

NOTE: The Y-axis shows 1% VO per division
