a u s t ri a m i c r o s y s t e m s AS1357 P r o g r a m m a b l e Tr i p l e L D O www.datasheet4u.com P ro du c t B ri e f 1 General Description The AS1357 is a high-performance triple CMOS lowdropout voltage regulator in a single 4x4 package. The efficient set of programmable power supplies is optimized to deliver the best compromise between quiescent current and regulator performance for mobile phones, PDAs, MP3 players, and other battery powered devices. The one-time-programmable (OTP) function provides greater design flexibility by allowing for independent programming of the output voltage for each regulator onsite. The OTP function allows for fast prototyping as well as full-production in the field. Factory trimmed versions are also available.
