ABSOLUTE MAXIMUM RATINGS
V IN , V MODE , V OUT and EN/PWM ................. -0.3V to 6V
Output Current (I OUT ) ...................................... 300mA
Power Dissipation per Package - 10-pin DFN
(derate 8.84mW/ ° C above +70 ° C) ..................... 1.2W
Junction Temperature .................................... +125 ° C
Storage Temperature ...................... -65 ° C to +150 ° C
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.
ESD Rating. ................................................ 2kV HBM
ELECTRICAL CHARACTERISTICS
Unless otherwise specified: V IN = 3.6V, C1 = C4 = 2.2 μ F & C2 = C3 = 1 μ F (Ceramic, ESR=0.03 ? ) and T AMB =25 ° .
The ? denotes specifications which apply over full operating temperature range -40oC to +85oC.
