Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 5. 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. 6. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details. 7. For θJC, the “case temp” location is taken at the package top center. Electrical Specifications TA = -40°C to +85°C; VIN = (VO + 0.5V) to 5.5V with a minimum VIN of 1.5V; CIN = 1µF; CO = 1µF. Boldface limits apply over the operating temperature range, -40°C to +85°C.
