7 / 22 page L4979D, L4979MD Electrical specifications Doc ID 10262 Rev 9 7/22 2 Electrical specifications 2.1 Absolute maximum ratings Stressing the device above the ratings listed in Table 3 may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not implied. Exposure to the conditions reported in this section for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE program and other relevant quality documents. Table 3. Absolute maximum ratings Symbol Parameter Value Unit Vvsdc DC supply voltage -0.3 to 40 V Ivsdc Input current Internally limited Vvo DC output voltage -0.3 to 6 (1) 1. Using the typical application schematic with Cout= 10 µF and Iout=0 A, when the regulator is switched-on, an overshoot exceeding 6 V could occur.This behavior does not impact the reliability of the regulator. V Ivo DC output current Internally limited Vwi Watchdog input voltage -0.3 to Vvo +0.3 V Vod Open drain output voltage (RES) -0.3 to Vvo +0.3 V Iod Open drain output current (RES) Internally limited Vcr Reset delay voltage -0.3 to Vvo +0.3 V Vcw Watchdog delay voltage -0.3 to Vvo +0.3 V Ven Enable input voltage -0.3 to 40 V Tj Junction temperature -40 to 150 °C VESD ESD voltage level (HBM-MIL STD 883C) ±2 kV Table 4.
