ESD HBM Human Body Mode ESD Protection 2 kV CDM Charged Device Model 500 V VIN Input Voltage -0.3 to 7 V VEN Input Voltage for EN Pin -0.3 to 7 V VPG Power Good Indictor Voltage -0.3 to 7 V VOUT Output Voltage -0.3 to VIN + 0.3 V VNR/SS VNR/SS Pin Voltage -0.3 to 2 V VFB Feedback Pin Voltage -0.3 to 2 V TJ Operating Junction Temperature 150 °C TSTG Storage Temperature -55 to +150 °C θJA Thermal Resistance Junction to Ambient (JA) 65.4 °C/W Notes: 4. a). Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to absolute-maximum-rated conditions for extended period may affect device reliability. b). Ratings apply to ambient temperature at +25°C. The JEDEC High-K board design used to derive this data was a 3 inch x 3 inch multilayer board with 1oz. internal power and ground planes and 2oz. copper traces on the top and bottom of the board.
