ELECTRICAL CHARACTERISTICS
Unless otherwise specified, these specifications in bold type apply over the operating ambient temperature of 0°C to
+70°C, VIN – VOUT = 5V, IOUT = 10mA,CIN = 0.1µF, COUT= 1.0µF, 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.)
