Product Summary

The LP3985ITLX-3.0 is a micropower, 150mA low-noise ultra low-dropout CMOS voltage regulator. It designed for portable and wireless applications with demanding performance and space requirements. The LP3985ITLX-3.0 is stable with a small 1μF ±30% ceramic or high-quality tantalum output capacitor. The micro SMD requires the smallest possible PC board area - the total application circuit area can be less than 2.0mm x 2.5mm, a fraction of a 1206 case size. Applications are (1)CDMA cellular handsets; (2)Wideband CDMA cellular handsets; (3)GSM cellular handsets; (4)Portable informatioappliances.
