AIC1750 11 application information the AIC1750 is a low-dropout, low quiescent-current, dual-output linear regulator for battery power applications. these parts are available with preset output voltages ranging from 1.1v to 3.3v, and the ly loads up to 150ma. e shut down to reduce the supply current to 0.1 a. this can protect the device from being damaged. rating of junction temperature must not be exceeded. ramic output capacitor for each regulator is d current? to choose proper ranges of voltage and temperature than other types. e low even when large is ssipation is: parts can supp shutdown the AIC1750 has two independent shutdown control inputs (en1 and en2). by connecting en1 pin to ground, output1 can be shut down. by connecting en2 pin to ground, output2 can be shut down. by connecting both of en1 pin and en2 pin to ground, the AIC1750 can b current limit the AIC1750 includes two independent current limiters, which monitor and control the maximum output current. if the output is overloaded or shorted to ground, thermal protection the AIC1750 includes two independent thermal- limiting circuits, which are designed to protect the device against overload condition. when the junction temperature exceeds t j =150oc, the thermal-limiting circuit turns off the pass transistor and allows the ic to cool. for continuous load condition, maximum input-output capacitors linear regulators require input and output capacitors to maintain stability. input capacitor at 1 f with a 1 f recommended. to avoid oscillation, it is recommended to follow the figure of ?region of stable c ce out esr vs. loa capacitor specifications. when choosing the input and output ceramic capacitors, x5r and x7r types are recommended because they retain their capacitance over wider power dissipation the maximum power dissipation of AIC1750 depends on the thermal resistance of its case and circuit board, the temperature difference between the die junction and ambient air, and the rate of airflow. the rate of temperature rise is greatly affected by the mounting pad configurati on on the pcb, the board material, and the ambient temperature. when the ic mounting with good thermal conductivity is used, the junction temperature will b power dissipation applies. the power dissipation across the device p = i out1 (v in -v out1 )+ i out2 (v in -v out2 ) the maximum power di ja max r where t a max-j )t-(t p = the ambient l conductivity to maintain low device temperature. j-max is the maximum allowable junction temperature (125 c), and t a is temperature suitable in application. as a general rule, the lower temperature is, the better reliability of the device is. so the pcb mounting pad should provide maximum therma
