Unless otherwise noted, all parameter limits are established across the recommended operating conditions and the specification limits

are measured at the following conditions: TA=-40°C to +125°C, VIN = 3.6V, VOUT = 1.2V, unless otherwise noted. Typical specifications

are measured at TA=+25°C. Boldface limits apply across the internal junction temperature range, -40°C to +125°C. (Cont.)
