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 Tel:(852)2341 9276 Fax:(852)2797 8153 E-mail: ic@wingshing.com Wing Shing Computer Components Co., (H.K.)Ltd.
