9 / 21 page L79xxC Electrical characteristics 9/21 Table 7. Electrical characteristics of L7915C (refer to the test circuits, TJ = 0 to 125 °C, VI = -23 V, IO = 500 mA, CI = 2.2 µF, CO = 1 µF unless otherwise specified) Symbol Parameter Test conditions Min. Typ. Max. Unit VO Output voltage TJ = 25°C -14.4 -15 -15.6 V VO Output voltage IO = -5 mA to -1 A, PO ≤ 15 W VI = -18.5 to -30 V -14.3 -15 -15.7 V ΔVO(1) Line regulation VI = -17.5 to -30 V, TJ = 25°C 300 mV VI = -20 to -26 V, TJ = 25°C 150 ΔVO(1) Load regulation IO = 5 mA to 1.5 A, TJ = 25°C 300 mV IO = 250 to 750 mA, TJ = 25°C 150 Id Quiescent current TJ = 25°C 3 mA ΔId Quiescent current change IO = 5 mA to 1 A 0.5 mA VI = -18.5 to -30 V 1 ΔVO/ΔT Output voltage drift IO = 5 mA -0.9 mV/°C eN Output noise voltage B = 10Hz to 100kHz, TJ = 25°C 250 µV SVR Supply voltage rejection ΔVI = 10 V, f = 120Hz 54 60 dB Vd Dropout voltage IO = 1 A, TJ = 25°C, ΔVO = 100 mV 1.1 V Isc Short circuit current 1.3 A 1. 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.
