STATIC ELECTRICAL CHARACTERISTICS
Table 3. Static Electrical Characteristics (continued)
Characteristics noted under conditions V_IN = 5.0V, -40°C ≤ T_A ≤ 85°C, C_IN =1µF, C_OUT = 2.2µF (see Figure 1), unless otherwise
noted. Typical values noted reflect the approximate parameter means at V_IN = 5.0V and T_A = 25°C under nominal conditions,
unless otherwise noted.
