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 of AS1351 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.

Stability is guaranteed with ceramic output capacitors of only 1F
(±20% . X5R) up to 4.7F (±20% . X5R). The low equivalent series resistance (ESR) of these capacitors AS1351 ensures low output impedance at high frequencies.

Regulation performance of AS1351 is excellent even under low dropout conditions, when the power transistor has to operate in linear mode.

The low-noise performance AS1351 allows direct connection of noise sensitive circuits without additional filtering networks.

The AS1351 is available in a 12-pin QFN 3x3 package or in a wafer bumping package.
