3 / 14 page Absolute Maximum Ratings (Note 1) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications. Power Dissipation (Note 5) Internally Limited Input Voltage 35V Storage Temperature −65˚C to +150˚C ESD Susceptibility (Note 2) 1kV Operating Junction Temperature SO-8, TO-92 0˚C to 125˚C micro SMD −40˚C to 85˚C Soldering Information Infrared or Convection (20 sec.) 235˚C Wave Soldering (10 sec.) 260˚C (lead time) LM78LXX Electrical Characteristics Limits in standard typeface are for T J = 25˚C, Bold typeface applies over 0˚C to 125˚C for SO-8 and TO-92 packages, and −40˚C to 85˚C for micro SMD package. Limits are guaran- teed by production testing or correlation techniques using standard Statistical Quality Control (SQC) methods. Unless other- wise specified: I O = 40mA, CI = 0.33µF, CO = 0.1µF.
