Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTE: 1. θ 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 Recommended operating conditions unless otherwise noted. Refer to Block Diagram and Typical Application Schematic. VIN = 5.6V to 24V, or VCC_5V = 5V ±10%, C_VCC_5V = 4.7µF, TA = -40°C to +85°C (Note 5), Typical values are at TA = +25°C, unless otherwise specified.
