1. Compliance to datasheet limit is assured by one or more methods: production test, characterization and/or design.

2. Compliance to limits is assured by characterization and design.

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.)
