3 / 12 page ACE432 Technology Precision adjustable shunt voltage reference VER 1.2 3 Power Dissipation Table Package θ JA ( OC /W ) Df(mW/℃) TA≧25℃ TA≤ 25 OC Power rating(mW) TA=50 OC Power rating(mW) TA= 75 OC Power rating (mW) EP 220 6.41 568 455 341 BM 230 3.50 543 435 326 Note: 1.Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into Thermal shutdown. 2.TJ: Junction Temperature Calculation TJ = TA + ( PD x θJA ) The θJA numbers are guidelines for the thermal performance of the device/PC-board system. All of the above assume no Ambient airflow. 3.θJA : Thermal Resistance-Junction to Ambient, DF: Derating factor, Po: Power consumption Electrical Characteristics Parameter Symbol Test Conditions Min.
