(1)

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

⅛ in.

below the base of the TO packages.

Selected devices with tightened tolerance reference voltage available.

6.5 Electrical Characteristics

Unless otherwise specified, these specifications apply: 0°C

limited, these specifications are applicable for power dissipations of 2 W for the TO and SOT-223, and 20 W for the TO-220.
