ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.
ELECTRICAL CHARACTERISTICS
Unless otherwise specified: V_IN = 3.6V, C1 = C4 = 2.2µF & C2 = C3 = 1µF (Ceramic, ESR=0.03Ω) and T_AMB =25°.
The ♦ denotes specifications which apply over full operating temperature range -40ºC to +85ºC.
