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: TA = -40°C to +85°C, VIN = 3.6V, EN = VIN, unless otherwise noted. Typical values are
at TA = +25°C. Boldface limits apply over the operating temperature range, -40°C to +85°C (Continued)
