6 / 26 page Analog Integrated Circuit Device Data 6 Freescale Semiconductor 34674 ELECTRICAL CHARACTERISTICS STATIC 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.
