The R1515 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, R1515 contains a thermal shutdown circuit. Besides the low supply current by CMOS, the operating temperature is -40°C to 105°C and the maximum input voltage is 36V, the R1515 series are very suitable for use in dig
