4 / 5 page ![]() USR1101 Preliminary LINEAR INTEGRATED CIRCUIT UNISONICTECHNOLOGIESCO.,LTD 4 of 5 www.unisonic.com.tw QW-R103-062.b ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC 16 V Power Dissipation (TA=25°C) (Note 1) PD 0.625 W Storage Temperature TSTG -65~150 °C Junction Temperature TJ 150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. THERMAL DATA PARAMETER SYMBOL RATINGS UNIT Junction to Ambient θJA 160 °С/W RECOMMENDED OPERATING CONDITIONS (Note 2) PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC 5±5%,12±10% V Ambient Temperature TA 0~70 °C Junction Temperature TJ 0~125 °C Notes: 1. θJA is measured in the natural convection at TA=25°C on a low effective thermal conductivity test board of JEDEC 51-3 thermal measurement standard. 2. The device is not guaranteed to function outside its operating conditions.
