CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTE:
5. θ JA 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 V IN = 1.2V, V OUT = 3.3V, T A = +25°C (see “Typical Application Circuits” on page 7). Boldface limits apply
over the operating temperature range, -20°C to +85°C.
