SYSTEM CHARACTERISTICS (continued)

The following spec table entries are ensured by design providing the component values in the typical application circuit are

used (L = 2.2 µH, DCR = 130 m

Ω, CIN = 10 µF, 6.3V, 0603 TDK C1608X5RJ106M, COUT = 4.7 µF + 4.7 µF, 6.3V, 0603,

C1608JB0J475). These parameters are not ensured by production testing. Min and Max values are specified over the

ambient temperature range TA = −30°C to 85°C. Typical values are specified at PVIN = VDD = EN = 3.6V, AUTO_BY = 3.6V

and TA = 25°C unless otherwise noted.
