VREF2 output current MIrefout2 3 mA VREF2 (Note) TC78B041FNG (SSOP30) PD1 1.87 W When mounted on JEDEC 4-layer board Power dissipation TC78B042FTG (QFN32) PD2 4.25 W When mounted on JEDEC 4-layer board Operating temperature range is determined according to the characteristics of power dissipation. The Operating temperature Topr - 40 to 115 °C maximum junction temperature should not exceed Tj (max) (150°C). Storage temperature Topr - 55 to 150 °C ― The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even for a moment. Do not exceed any of these ratings. Exceeding the rating (s) may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion. Please use the IC within the specified operating ranges. Note: VREF2 pin is only for the TC78B042FTG. 10 2018-11-27
