ELECTRICAL CHARACTERISTICS

STATIC ELECTRICAL CHARACTERISTICS

Table 4. Static Electrical Characteristics

Characteristics noted under conditions VIN = 5.0V, -40°C ≤ TA ≤ 85°C, CIN = COUT = 1µF (see Figure 1), unless otherwise

noted. Typical values noted reflect the approximate parameter means at VIN = 5.0V and TA = 25°C under nominal conditions,

unless otherwise noted.
