OUTLINE

The R1524x is a CMOS-based 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

−40°C to 105°C, 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 at either of the following: 1.8 V, 2.5 V, 2.8 V, 3.0 V, 3.3 V, 3.4 V, 5.0 V,

6.0 V, 8.0 V, 8.5 V and 9.0 V. 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 a 5-pin SOT-23-5, a 5-pin SOT-89-5, a 6-pin HSOP-6J, and a 6-pin DFN(PLP)1820-6 package.
