11 / 24 page L79xxC Electrical characteristics 11/24 Table 11. Electrical characteristics of L7924C (refer to the test circuits, TJ = 0 to 125 °C, VI = -33 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 -23 -24 -24.5 V VO Output voltage IO = -5 mA to -1 A, PO ≤15 W VI = -27 to -38 V -22.8 -24 -25.2 V ΔVO(1) Line regulation VI = -27 to -38 V, TJ = 25°C 480 mV VI = -30 to -36 V, TJ = 25°C 240 ΔVO(1) Load regulation IO = 5 mA to 1.5 A, TJ = 25°C 480 mV IO = 250 to 750 mA, TJ = 25°C 240 Id Quiescent current TJ = 25°C 3 mA ΔId Quiescent current change IO = 5 mA to 1 A 0.5 mA VI = -27 to -38 V 1 ΔVO/ΔT Output voltage drift IO = 5 mA -1 mV/°C eN Output noise voltage B = 10Hz to 100kHz, TJ = 25°C 400 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 1.1 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. |
