8 / 24 page Electrical characteristics L7900 series 8/24 Table 6. Electrical characteristics of L7912C (refer to the test circuits, TJ = 0 to 125°C, VI = -19V, 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 -11.5 -12 -12.5 V VO Output voltage IO = -5 mA to -1 A, PO ≤15 W VI = -15.5 to -27 V -11.4 -12 -12.6 V ∆VO(1) Line regulation VI = -14.5 to -30 V, TJ = 25°C 240 mV VI = -16 to -22 V, TJ = 25°C 120 ∆VO(1) Load regulation IO = 5 mA to 1.5 A, TJ = 25°C 240 mV IO = 250 to 750 mA, TJ = 25°C 120 Id Quiescent current TJ = 25°C 3 mA ∆Id Quiescent current change IO = 5 mA to 1 A 0.5 mA VI = -15 to -30 V 1 ∆VO/∆T Output voltage drift IO = 5 mA -0.8 mV/°C eN Output noise voltage B = 10Hz to 100KHz, TJ = 25°C 200 µV SVR Supply voltage rejection ∆VI = 10 V, f = 120Hz 54 60 dB Vd Dropout voltage IO = 1 A, TJ = 25°C, ∆VO = 100 mV 1.1 V Isc Short circuit current 1.5 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.
