R1524x Series 200 mA 36 V Input Ultra Low Supply Current VR No. EA-332-200310 OUTLINE The R1524x is an ultra-low supply current voltage regulator featuring 200 mA output current and 36 V input voltage. This device consists of an Output Short-circuit Protection Circuit, an Over-current Protection Circuit, and a Thermal Shutdown Circuit in addition to the basic regulator circuits. The operating temperature range is from 40C to 105C, and the maximum input voltage is 36 V. All these features allow the R1524x to become an ideal power source of electric home appliances. The output voltages are internally fixed (refer to SELECTION GUIDE). The output voltage accuracy is 0.6%. The packages for this device range from high-density mounting to ultra high wattage. The R1524x is offered in five packages a 5-pin SOT-23-5, a 5-pin SOT-89-5, a 6-pin HSOP-6J, a 6-pin DFN(PLP)1820-6, and an 8- pin HSOP-8E package.
