Electrical Characteristics
Note 1: Unless otherwise specified, these specifications apply −55˚C ≤ T
= 0.1A for the TO-39 package and I
are applicable for power dissipations of 2W for the TO-39 and SOT-223 (see Application Hints), and 20W for the TO-3, and TO-220. I
SOT-223 and TO-220 packages, and 0.2A for the TO-39 package.
Note 2: Regulation is measured at constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are
covered under the specification for thermal regulation. Load regulation is measured on the output pin at a point
Note 3: Selected devices with tightened tolerance reference voltage available.
