STATIC ELECTRICAL CHARACTERISTICS
Table 5. Static Electrical Characteristics (continued)
Characteristics noted under conditions - 40 °C ≤ T_A ≤ 85 °C, GND = 0 V unless otherwise noted. Typical values noted reflect
the approximate parameter means at T_{A =} 25 °C under nominal conditions, unless otherwise noted.

Notes
34. Preferred device TDK VLS252012 series at 2.5x2.0 mm footprint and 1.2 mm max height
35. Applications of SWBST should take into account impact of tolerance and voltage derating on the bypass capacitor at the output level.
