R1501x SERIES AEC-Q100 Grade2 Compliant 1 A LDO Regulator (Operating Voltage up to 24 V) for Automotive Applications NO.EC-184-160801 OUTLINE The R1501x is a CMOS-based positive voltage regulator (VR) IsCp ecifically designed for automotive applications. The R1501xxxxB has features of high input voltage operating, 1 A output current drive, and low supply current. *1 A DMOS transistor is used for the driver, high voltage operating and low on resistance (0.6 at VOUT = 10 V) device is realized. A standard regulator circuit with a current limit circuit and a thermal shutdown circuit are built in this IC. As the operating temperature range is from 40C to 105C and maximum input voltage is up to 24 V, this IC is suitable for the constant voltage source for car accessories. The regulator output voltage is fixed in this IC. Output voltage accuracy is 2.0% and output voltage range is from 3.0 V to 12.0 V with a step of 0.1 V, and from 12.5 V to 18.0 V with a step of 0.5 V. The chip enable pin realizes ultra low supply current standby mode. The packages for this IC are the HSOP-6J for high density mounting of the IC on boards, and the TO-252-5-P2 for high wattage. *1 The DMOS (Double Diffused MOS) transistor adopted by this IC is characterized by a double diffusion structurewh ich 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. This IC possesses outstanding properties of high operating voltage and low on-resistance, which have been achieved by the channel length scaled down to submicron dimensions anddec reased thickness of the gate oxide film.
