10.5V Input, p , Low Power Consumption, p , High g Speed 200mA LDO Regulator New Product Release XC6505 Series Digital Camera Camcorder The XC6505 series of LDO regulators achieve a load-transient response characteristic (ripple rejection ratio of 60dB at 1kHz) on the same level as regular highspeed LDOs with a very small supply current of only 5.5μA. An input voltage range from 1.7V to as high as 10.5V is supported. These regulators are ideal for applications that operate on two-cell Li-ion batteries, four 1.5V dry-cell batteries, and rectangular 9V dry-cell batteries, and in applications that supply 5V at the back end of a 6V output DC/DC. Operation at 105㷄 can be guaranteed for in-vehicle accessories and industrial equipment applications.

New Product Release High Speed 200mA LDO Regulator䇭XC6505 Series 4 Product development concept In many instances, multiple regulators are necessary to handle different types of control applications such as audio and video in car navigation and other multimedia devices. For example, a high speed response is required for video processing, and a low supply current is desirable for backup power supplies for which there are normally almost no fluctuations of load. The XC6505 achieves both a high speed response and a low supply current, making it possible to use a common regulator in multimedia devices that previously required different types of regulators. Using a common regulator shortens evaluation time and results in lower cost. The XC6505 can be used in high ambient temperatures such as in-vehicle accessories, and expands the temperature range (-40㷄 to 105㷄) over previous products to allow for self heating caused by step-down from a high input voltage. Along with expansion of the temperature range, we reexamined the internal reference power at the device level and achieved a temperature characteristic of ±30ppm/㷄 (Fig. 1). Through improvement of the temperature characteristic and a high-speed response characteristic, the XC6505 supplies a more stable output voltage.
