1 / 11 page AS1355 300mA, Tr iple LDO www.austriamicrosystems.com Revision 0.08 1 - 11 Preliminary Datasheet 1 General Description The AS1355 is a high-performance triple CMOS low- dropout voltage regulator in a single QFN package. The efficient set of programmable power supplies is opti- mized to deliver the best compromise between quies- cent current and regulator performance for mobile phones, PDAs, MP3 players, and other battery powered devices. Stability is guaranteed with ceramic output capacitors of only 1µF (±20% – X5R) up to 4.7µF (±20% – X5R). The low equivalent series resistance (ESR) of these capaci- tors ensures low output impedance at high frequencies. Regulation performance is excellent even under low dropout conditions, when the power transistor has to operate in linear mode. The low-noise performance allows direct connection of noise sensitive circuits without additional filtering net- works. The AS1355 is available in a 16-pin QFN 3x3 package. Figure 1.
