Description

The AS1352 is a high-performance quad CMOS lowdropout voltage regulator in a single 3x3mm and 4x4mm QFN 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 of AS1352 allows for fast prototyping as well as full-production in the field. Factory trimmed versions are also available.

Stability of AS1352 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 ensures low output impedance at high frequencies.

Regulation performance of AS1352 is excellent even under low dropout conditions, when the power transistor has to operate in linear mode.

The low-noise performance of AS1352 allows direct connection of noise sensitive circuits without additional filtering networks.

The AS1352 is available in a 16-pin QFN 3x3 package and in a 12-pin QFN 4x4 package.
