Although power dissipation is internally limited, these specifications are applicable for power dissipation up to 625mW. IMAX is 100mA Regulation is measure 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. Thermal resistance of the TO-92 package is 180℃/W junction to ambient with 0.4” leads from a PC board and 160 ℃/W junction to ambient with 0.125” length to a PC board Wing Shing Computer Components Co., (H.K.)Ltd.
