3 / 10 page LM2937 LINEAR INTEGRATED CIRCUIT UNISONICTECHNOLOGIESCO.,LTD 3 of 10 www.unisonic.com.tw QW-R102-012.G ABSOLUTE MAXIMUM RATINGS (Note 1) PARAMETER SYMBOL RATINGS UNIT Input Voltage VIN 26 V Power Dissipation(Note 2) PD Internally limited Maximum Junction Temperature TJ +150 °C Storage Temperature TSTG -40 ~ +150 °C Note 1. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical Specifications do not apply when operating the device outside of its rated Operating Conditions. 2. The maximum allowable power dissipation at any ambient temperature is PMAX = (125-TA)/ θJA, where 125 is the maximum junction temperature for operation, TA is the ambient temperature, and θJA is the junction to ambient thermal resistance. If this dissipation is exceeded, the die temperature will rise above 125 °C and the electrical specifications do not apply. If the die temperature rises above 150 °C, the LM2937 will go into thermal shutdown.
