Unless otherwise specified, these specifications apply for (VIN - VOUT) = 5.0V and IOUT = 1.5A. Although power dissipation is internally limited, these characteristics are applicable for power dissipation up to 30W. 2. Regulation is measured at a constant junction temperature using a pulse technique. Changes in output voltage due to heating effects are covered under the specification for thermal regulation. 3.
