Designing with LDOs

Click image to enlarge

Figure 1: The challenge of dynamic performance vs. current consumption has been addressed by introducing parts that are switchable between low power mode and high performance. A typical example is ON Semiconductor's NCP4587.
Looking at products that are currently sampling, it appears that products with noise in the 10 ?VRMS range and Quiescent current in the 10-15 μA range will be in production by the end of this year, giving cell phone designers the best of both worlds in selecting their LDOs.

Low drop-out Linear voltage regulators are a vital component in a wide range of applications; perhaps some of the most demanding conditions exist in the portable equipment (media players, digital
