Note 1. Although power dissipation is internally limited, these specifications are applicable for power
dissipations of 625mW.
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.
Note 3. Thermal resistance is 180°C/W junction to ambient with 0.4” leads from a PC board and
160°C/W junction to ambient with 0.125” lead length to PC board.
