6 / 13 page L7900AC SERIES 6/13 Table 9: Electrical Characteristics Of L7918A (refer to the test circuits, TJ = 0 to 125°C, VI = -27V, IO = 500 mA, CI = 2.2 µF, CO = 1 µF unless otherwise specified). (*) 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 cycle is used. Table 10: electrical characteristics of L7920A (refer to the test circuits, TJ = 0 to 125°C, VI = -29V, IO = 500 mA, CI = 2.2 µF, CO = 1 µF unless otherwise specified). (*) 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 cycle is used.
