Although power dissipation is internally limited, these specifications are applicable for power dissipations up to 625mW. IMAX is 100mA. (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. (3) Thermal resistance of the TO-92 package 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.
