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.
V IN , V MODE , V OUT , EN/PWM ............................ -0.3V to 6.0V
V IN - V OUT .............................................................. 0.7V
Output Current I OUT ............................................ 300mA
Power Dissipation (10-pin MSOP)
(derated 8.84mW/°C above +70°C) .....................720mW
Junction Temperature Range .............................. +125°C
Storage Temperature ..............................-65°C to 150°C
ESD Rating (HBM - Human Body Model) .................... 2kV
ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Ambient Temperature of T A = 25°C only; limits applying over the full
Operating Ambient Temperature range are denoted by a “?”. Minimum and Maximum limits are guaranteed through test,
design, or statistical correlation. Typical values represent the most likely parametric norm at T A = 25°C, and are provided
for reference purposes only. Unless otherwise indicated, V IN = 2.7V to 5.0V, C 1 =C 2 =C 4 =C 5 =2.2μF (ceramic, ESR=0.03 ? ),
C 3 =0.1μF (ceramic), T A = –40°C to 85°C.
