2 / 18 page KA79XX/KA79XXA 2 Absolute Maximum Ratings Note: 1. Thermal resistance test board Size: 76.2mm * 114.3mm * 1.6mm(1S0P) JEDEC standard: JESD51-3, JESD51-7 2. Assume no ambient airflow Electrical Characteristics (KA7905) (VI = -10V, IO = 500mA, 0 °C ≤ TJ ≤ +125°C, CI =2.2µF, CO =1µF, unless otherwise specified.) Note 3. 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.
