2 / 28 page  LM78XX (KA78XX, MC78XX) FIXED VOLTAGE REGULATOR (POSITIVE) ABSOLUTE MAXIMUM RATINGS (T A = +25 °C, unless otherwise specified) LM7805/I/R/RI ELECTRICAL CHARACTERISTICS (Refer to test circuit, TMIN < TJ < TMAX, IO = 500mA, VI = 10V, CI= 0.33 µF, C O= 0.1 µF, unless otherwise specified) * TMIN <TJ <TMAX LM78XXI/RI: TMIN= - 40 °C, T MAX = +125 °C LM78XX/R: TMIN= 0 °C, T MAX= +125 °C * Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately. Pulse testing with low duty is used.
