Table 3. Static Electrical Characteristics (continued)

Characteristics noted under conditions VIN = 5V, -40°C ≤ TA ≤ 85°C, CIN = 1.0μF, COUT = 2.2μF, CDET = 0.22μF (see Figure 1),

unless otherwise noted. Typical values noted reflect the approximate parameter means at VIN = 5V and TA = 25°C under nominal

conditions, unless otherwise noted.
