Consult factory for parts specified with wider operating temperature ranges.
ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. (VIN = 2.6V to 6V, DVCC = 1.425V to 4.4V, controller digital pins tied to
DVCC, SIM digital pins floating, C1 = 0.1µF, COUT = 2.2µF unless otherwise noted)
