Electrical Specifications
Unless otherwise noted, all parameter limits are established over the recommended
operating conditions and the typical specification are measured at the following conditions
unless otherwise noted: TA = -40°C to +85°C, VIN = 3.6V, EN = VDD. Typical values are at
TA = +25°C. Boldface limits apply over the operating temperature range,
-40°C to +85°C. (Continued)
