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 AS13985 is perfectly suited for mobile phones, PDAs, MP3 players, and other battery powered devices.
Stability of AS13985 is guaranteed with a ceramic output capacitor of from 1 to 22F. The low equivalent series resistance (5) of these capacitors ensures low output impedance at high frequencies. Automatic sleep mode requires less than 1A quiescent current when pin EN is pulled low.
Regulation performance of AS13985 is excellent even under low dropout conditions, when the power transistor AS13985 has to operate in linear mode. A 10nF bypass capacitor can be added to reduce output noise to 30V. The low-noise performance allows direct connection of noise sensitive circuits without additional filtering networks.
Multiple output voltage options of AS13985 from 1.2 to 5.0V 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.
