Converters, Dual LDOs, and RESET
ELECTRICAL CHARACTERISTICS (continued)
(V_PV1 = 13.5V, V_PV2 = V_PV3 = V_OUT1, V_PV4 = V_OUT2; T_A = T_J = -40°C to +125°C, unless otherwise noted. Typical values are at
T_A = +25°C under normal conditions, unless otherwise noted.) (Note 2)

Note 2: All units are 100% production tested at T_A = +25°C. All temperature limits are guaranteed by design.
Note 3: Once PVI exceeds undervoltage-lockout rising threshold 4.0V and the device is in regulation.
Note 4: Guaranteed by design. Not product tested.
