8 / 18 page KA79XX/KA79XXA 8 Electrical Characteristics (KA7915) (Continued) (VI = -23V, IO = 500mA, 0 °C ≤TJ ≤ +125°C, CI =2.2µF, CO =1µF, unless otherwise specified.) Note 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 is used. Parameter Symbol Conditions Min. Typ. Max. Unit Output Voltage VO TJ = +25 °C -14.4 -15 -15.6 V IO = 5mA to 1A, PO ≤ 15W VI = -18V to -30V -14.25 -15 -15.75 Line Regulation (Note1) ∆VO TJ = +25 °C VI = -17.5V to -30V - 12 300 mV VI = -20V to -26V - 6 150 Load Regulation (Note1) ∆VO TJ = +25 °C, IO = 5mA to 1.5A - 12 300 mV TJ =+25 °C, IO = 250mA to 750mA - 4 150 Quiescent Current IQ TJ =+25 °C- 3 6 mA Quiescent Current Change ∆IQ IO = 5mA to 1A - 0.05 0.5 mA VI = -17.5V to -30V - 0.1 1 Temperature Coefficient of VD ∆Vo/∆TIO = 5mA - -0.9 - mV/ °C Output Noise Voltage VN f = 10Hz to 100kHz, TA = +25 °C - 250 - µV Ripple Rejection RR f = 120Hz, ∆VI = 10V 54 60 - dB Dropout Voltage VD TJ = +25 °C, IO = 1A - 2 - V Short Circuit Current ISC TJ = +25 °C, VI = -35V - 300 - mA Peak Current IPK TJ = +25 °C- 2.2 - A |
