| Datasheet AS13985 Micropower 150mA Low-Noise LDO 1 General Description The AS13985 is a high-performance low-dropout 150mA voltage regulator designed for use with very-low ESR output capacitors. The device can deliver superior performance in all specifications critical to battery-powered designs, and is perfectly suited for mobile phones, PDAs, MP3 players, and other battery powered devices. Stability is guaranteed with a ceramic output capacitor from 1 to 22µF. The low equivalent series resistance of these capacitors ensures low output impedance at high frequencies. Automatic sleep mode requires less than 1µA quiescent current when pin EN is pulled low. Regulation performance is excellent even under low dropout conditions, when the power transistor has to operate in linear mode. A 10nF bypass capacitor can be added to reduce output noise to 30µV. The low-noise performance allows direct connection of noise sensitive circuits without additional filtering networks. Multiple output voltage options are available as standard products. Contact austriamicrosystems AG for details. The AS13985 is available in a 5-bump WLP package and a 5-pin SOT23 package. Figure AS13985 - Block Diagram 2 Key Features !
