R1500x SERIES 500mA LDO REGULATOR (Operating Voltage up to 24V) NO.EA-151-130416 OUTLINE The R1500x series are CMOS-based positive voltage regulator (VR) ICs. The R1500xxxxB has features of high input voltage operating, 500mA output current drive, and low supply current. A DMOS transistor is used for the driver, high voltage operating and low on resistance (0.6Ω at VOUT=10V) device is realized. A standard regulator circuit with a current limit circuit and a thermal shutdown circuit are built in the R1500x series. As the operating temperature range is from -40°C to 105°C and maximum input voltage is up to 24V, the R1500x series are suitable for the constant voltage source for car accessories. The regulator output voltage is fixed in the R1500x. Output voltage ac
