R1524x Series
200 mA 36 V Input Ultra Low Supply Current VR
NO.EA-332-160720
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.
