R1500J (TO-252-5-P2) is the discontinued product as of July, 2016. R1500x SERIES 500 mA LDO REGULATOR (Operating Voltage up to 24 V) NO.EA-151-160701 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 (0.6 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 -40C to 105C 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 accuracy is 2.0% and output voltage range is from 3.0V to 12.0V with a step of 0.1V. The chip enable pin realizes ultra low supply current standby mode. Since the packages for these ICs are the SOT -89-5 for high density mounting of the ICs on boards, and the TO- 252-5-P2. ) The DMOS (Double Diffused MOS) transistor adopted by R1500x is characterized by a double diffusion structure which comprises a low density n-type (channel) diffused layer and a high density p-type (sources) diffused layer from the edge of the gate electrode. The R1500x series possess outstanding properties of high operating voltage and low on-resistance, which have been achieved by the channel length scaled down to submicron dimensions and decreased thickness of the gate oxide film.
