Electrical Characteristics
Unless otherwise noted, VIN = 2.5V to 5.5V, CIN (IN1–6) = 4.7 µF, COUT (VO1 and VO9) = 4.7 µF, COUT (VO2, VO3, VO7, VO8, VO10
and VO11) = 2.2 µF, COUT (VO4 to VO6) = 1 µF, COUT (VRTC) = 1 µF ceramic, CBYP = 0.1 µF. Typical values and limits appearing in
normal type apply for TJ = 25°C. Limits appearing in boldface type apply over the entire junction temperature range for operation,
−40 to +125°C. (Note 2, Note 8, Note 9, Note 10)
