R1501x SERIES 1A LDO REGULATOR (Operating Voltage up to 24V) NO.EA-184-130507 OUTLINE The R1501x series are CMOS-based positive voltage regulator (VR) ICs. The R1501xxxxB has features of high input voltage operating, 1A 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 R1501x series. As the operating temperature range is from -40C to 105C and maximum input voltage is up to 24V, the R1501x series are suitable for the constant voltage source for digital home appliances and car accessories. The regulator output voltage is fixed in the R1501x. Output voltage accuracy is 2.0% and output voltage range is from 3.0V to 12.0V with a step of 0.1V, and from 12.5V to 18.0V with a step of 0.5V. The chip enable pin realizes ultra low supply current standby mode. Since the packages for these ICs are the HSOP-6J for high density mounting of the ICs on boards, and the TO-252-5-P2. ) The DMOS (Double Diffused MOS) transistor adopted by R1501x 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 R1501x 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.

ABSOLUTE MAXIMUM RATINGS Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent damages and may degrade the life time and safety for both device and system using the device in the field. The functional operation at or over these absolute maximum ratings is not assured. RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS) All of electronic equipment should be designed that the mounted semiconductor devices operate within the recommended operating conditions. The semiconductor devices cannot operate normally over the recommended operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And the semiconductor devices may receive serious damage when they continue to operate over the recommended operating conditions. 4 R1501x ELECTRICAL CHARACTERISTICS * R1501xxxxB VIN=VSET+1.0V, VCE=VIN, unless otherwise noted.

For this purpose, use a capacitor C2 with good frequency characteristics and ESR (Equivalent Series Resistance). If you use a tantalum type capacitor and ESR value of the capacitor is large, output might be unstable. Evaluate your circuit with considering frequency characteristics. Depending on the capacitor size, manufacturer, and part number, the bias characteristics and temperature characteristics are different. Evaluate the circuit with actual using capacitors. PCB Layout Make VDD and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect a capacitor C1 with a capacitance value as much as 0.47F or more between VDD and GND pin, and as close as possible to the pins. Set external components, especially the output capacitor C2, as close as possible to the ICs, and make wiring as short as possible. No.2 pin, No.3 pin and No.5 pin of HSOP-6J package must be wired to the GND plane when it is mounted on board. No.2 pin and No.3 pin of TO-252-5-P2 package must be wired to the GND plane when it is mounted on board. 6 R1501x TYPICAL APPLICATION FOR PREVENTING IC DESTRUCTION D1 VDD C1 VOUT R1501x Series CE VOUT C2 D2 GND C1: 0.47F or more (preventing for unstable operation) C2: 10F or more (preventing for unstable operation) D1: If VOUT pin could be higher than VIN pin, D1 is necessary.

consider the following points: The relations between IOUT (Output Current) and ESR of an output capacitor are shown below. The conditions when the white noise level is under the specified certain level are marked as the hatched area in the graph.
