6 Specifications

6.1 Absolute Maximum Ratings

See (1).
MIN MAX UNIT
Power dissipation Internally limited
Input–output voltage differential −0.3 60 V
Lead temperature (soldering, 10 seconds) 300 °C
Storage temperature, Tstg −65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM)(1) ±2000 V
(1) Manufacturing with less than 500-V HBM is possible with the necessary precautions.

6.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)
MIN MAX UNIT
Operating junction temperature 0 125 °C

(1) Unless otherwise specified, these specifications apply: 0°C ≤ TJ ≤ +125°C; VIN − VOUT = 5 V and IOUT = 0.1 A for the TO-39 package and IOUT = 0.5 A for the TO-3 and TO-220 packages. Although power dissipation is internally limited, these specifications are applicable for power dissipations of 2 W for the TO-39 and 20 W for the TO-3 and TO-220. IMAX is 1.5 A for the TO-3 and TO-220 and 0.5 A for the TO-39 package.
(2) Regulation is measured at constant junction temperature. Changes in output voltage due to heating effects must be taken into account separately. Pulse testing with low duty cycle is used.
