Notes
18.
Preferred device TDK VLS252012 series at 2.5x2.0 mm footprint and 1.2 mm max height
19.
Applications of SWBST should take into account impact of tolerance and voltage derating on the bypass capacitor at the output level.
20.
The typical value represents the nominal rated value of the capacitor and takes into account the strong derating as a function of DC
voltage.
Table 5. Static Electrical Characteristics (Continued)
Currents valid over entire operating temperature range, except at 25°C only. Current in RTC Mode is from LICELL = 2.5 V, in
all other modes from BP = 3.6 V. External loads are not included.
