R1516x Series
150mA 36V Input LDO Regulator
NO.EA-258-140703
OUTLINE
The R1516x Series are CMOS-based high-voltage resistant and low supply current voltage regulator ICs that
provide the minimum 150mA of output voltage. Internally, the R1516x Series consists of a Foldback Protection
Circuit, and a Thermal Shutdown Circuit in addition to the basic regulator circuits. The operating temperature
range is between –40ºC to 105ºC, and the maximum input voltage is 36V. All these features allow the R1516x
Series to become an ideal power source of electric home appliances.
The R1516x Series are available in fixed output voltage options between 1.8V and 6.2V in 0.1V steps. The
output voltage accuracy is ±1%.
The R1516x Series are available in two types of packages: SOT-89-5 that is for high-density mounting and
HSOP-6J that is for high wattage.
