(2) Junction-to-ambient thermal resistance is highly application and board-layout dependent. In applications where high maximum power dissipation exists, special care must be paid to thermal dissipation issues in board design. (3) Min and Max limits are specified by design, test, or statistical analysis. Typical numbers represent the most likely norm. (4) Low ESR Surface-Mount Ceramic Capacitors (MLCCs) are used in setting electrical characteristics. (5) Typical values and limits appearing in normal type for TJ = 25°C. Limits appearing in boldfacetype apply over the entire junction temperature range for operation, −40°C to +125°C.
