ELECTRICAL CHARACTERISTICS
Unless otherwise specified, these specifications in bold type apply over the operating temperature range of
0OC ≤ TJ ≤ +150OC, VIN = -10V,IOUT = 40mA,CIN = 0.33µF, COUT= 0.1µF, and are for DC characteristics only. (Low
duty cycle pulse testing techniques are used which maintains junction and case temperatures equal to the ambient
temperature.)
