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.

Storage Temperature.............................. -65°C to 150°C

Junction Temperature .......................................... 150°C

Power Dissipation ................................ Internally Limited

Lead Temperature (Soldering, 5 sec) ..................... 260°C

ESD Rating (HBM - Human Body Model) .................... 2kV

OPERATING RATINGS

Junction Temperature Range ................. -40°C to +125°C

Note 1: The maximum allowable power dissipation is a

function of maximum operating junction temperature,

maximum allowable power dissipation at any ambient

the maximum allowable power limit will result in excessive

die temperature; thus, the regulator will go into thermal

shutdown

ELECTRICAL SPECIFICATIONS

Operating Junction Temperature range are denoted by a “•”. Minimum and Maximum limits are guaranteed through test,
