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 +105°C, VIN = 3.6V, EN = VDD. Typical values
are at TA = +25°C. Boldface limits apply across the operating temperature range, -40°C to +105°C. (Continued)
