Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTE: 5. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details. Electrical Specifications VIN = 1.2V, VOUT = 3.3V, TA = +25°C (see “Typical Application Circuits” on page 7). Boldface limits apply over the operating temperature range, -20°C to +85°C.
