概述
The R1500 Series are CMOS-based voltage regulators featuring 500mA output current and 24V input voltage. R1500 provides high input voltage operation and low on-resistance (at VSET=10V, below 0.6Ω) because of using DMOS transistor. In addition to a fold-back protection circuit built into conventional regulators, R1500 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 R1500 series are very suitable for power source of car accessories.
