……………………………………………….0.83W MSOP8 .. 150 ... 65... °C/W Junction Temperature...150°C
Notes:
Lead Temperature ..260°C 1) Exceeding these ratings may damage the device. Storage Temperature... -65°C to +150°C 2) The maximum allowable power dissipation is a function of the maximum junction temperature. TJ(MAX) the junction-to- ambient thermal resistance. θJA and the ambient temperature, TA the maximum allowable power dissipation at any ambient temperature is calculated using: PD(MAX)=(TJ(MAX)-TA)/ θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB.
