R1500x Series
500mA 24V Input VR
The R1500x Series are CMOS-based voltage regulators featuring 500mA output current and 24V input voltage. R1500x provides high
input voltage operation and low on-resistance (at VOUT = 10V, below 0.6Ω) because of using CMOS transistor. In addition to a fold-back
protection circuit built into conventional regulators, R1500x 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 24V, the R1515x series are very suitable for
power source of car accessories.
