Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 6. Absolute maximum voltage rating is defined as the voltage applied for a lifetime average duty cycle above 6V of 1%. 7. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech Brief TB379. 8. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside. 9. Extended operation at these conditions may compromise reliability. Exceeding these limits will result in damage. Recommended operating conditions define limits where specifications are guaranteed. 10. Electromigration specification defined as lifetime average junction temperature of +110°C where max rated DC current = lifetime average current. Electrical Specifications Unless otherwise noted, VIN = VOUT + 0.4V, VOUT = 1.8V, CIN = COUT = 10µF, TJ = +25°C, ILOAD = 0A. Applications must follow thermal guidelines of the package to determine worst case junction temperature. Please refer to “ISL78310 Schematic Block Diagram” on page 4 and Tech Brief TB379. Boldface limits apply over the operating temperature range, -40°C to +125°C.
