AS1355
300mA, Triple LDO
wwwams.com/LDOs/AS1355
Revision 1.3
1 - 12
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 optimzed to deliver the best
compromse between quiescent current and regulator performance
for mobile phones, PDAs, MP3 players, and other battery powered
devices.
Stability is guaranteed with ceramc output capacitors of only 1μF
(±20% – X5R) up to 4.7μF (±20% – X5R). The low equivalent series
resistance (ESR) of these capacitors 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 networks.
The AS1355 is available in a 16-pin QFN 3x3 package.
