R1516x SeriesAEC-Q100 Compliant

150mA 36V Input LDO Regulator for Automotive Application


Data Sheet

Data Sheet

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 this device to become an ideal power source for car accessories and ECUs.
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 ultra high wattage.
