Specifications over the –40°C to 125°C operating junction temperature range are assured by design, characterization and correlation with statistical process controls. The The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TJ = 25°C. VVIN1/2 = 15V, VBST1/2 = open, VRT/SYNC = 2V, VVOUT1/2 = open, unless otherwise specified. |
