That 25C is going to be terribly > inefficient for my snowplow engine control system (or whatever). > :) was trying to put a constraint since we do know that leakage changes over temperature profile and the fact that operating temperature ranges vary depending on device and market. rephrased again below: - opp-microamp: The maximum current drawn by the device in microamperes considering system specific parameters (such as transients, process, aging, maximum operating temperature range etc.) as necessary. This may be used to set the most efficient regulator operating mode. -- Regards, Nishanth Menon
