Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTE: 5. JA 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. 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; Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are not production tested.
