Application Information

Like any low-dropout regulator, the EUP7180 requires external capacitors for regulator stability. The EUP7180 is specifically designed for portable applications requiring minimum board space and smallest components. These capacitors must be correctly selected for good performance. Input Capacitor A minimum input capacitance of 1µF is required between the EUP7180 input pin and ground (the amount of the capacitance may be increased without limit).This capacitor must be located a distance of not more than 1cm from the input pin and returned to a clean analog ground. Any good quality ceramic, tantalum, or film capacitor may be used at the input. If a tantalum capacitor is used at the input, it must be guaranteed by the manufacturer to have a surge current rating sufficient for the application. Output Capacitance The EUP7180 is specifically designed to employ ceramic output capacitors as low as 1µF. Ceramic capacitors below 10µF offer significant cost and space savings, along with high frequency noi se filtering. Higher values and other types and of capacitor may be used, but their equivalent series resistance (ESR) should be maintained below 0.5Ω. Ceramic capacitor of the value required by the EUP7180 are available in the following dielectric types: Z5U, Y5V , X5R, and X7R. The Z5U and Y5V types exhibit a 50% or more drop in capacitance value as their temperature increase from 25°C, an important consideration. The X5R generally maintain their capacitance value within ± 20%. The X7R type are desirable for their tighter tolerance of 10% over temperature.
