a u s t ri a m i c r o s y s t e m s AS1351 Programmable Dual LDO www.datasheet4u.com P ro du c t B ri e f 1 General Description The AS1351 is a high-performance dual CMOS lowdropout voltage regulator in a single 3x3 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.
