Description

The R8151 Series are CMOS-based voltage regulators featuring 50mA output current and 36V input voltage. In addition to a fold-back protection circuit built into conventional regulators, R8151 contains a thermal shutdown circuit. Besides the low supply current by CMOS, the operating temperature is -40°C to 110°C and the maximum input voltage is 36V, the R8151 series are very suitable for use in automotive applications.
