The value of θJA is measured with the device mounted on a 1-in2 Notes: FR-4 four layer board with 2oz copper and Vias, in a still air environ- ment with T 1. Exceeding the Absolute Maximum ratings may damage the device. A = 25°C. The value in any given application depends on the user’s specification board design. 2. Devices are inherently ESD sensitive, handling precautions are required. Human body model rating: 1.5k in series with 100pF. Electrical Characteristics TA = 25°C, VIN = VEN = 12V, VOUT = 3.3V, unless otherwise specified. Specifications in Bold indicate an ambient temperature range of -40°C to +85°C. These specifications are guaranteed by design.
