AS1352

AS1352 Programmable Quad LDO Data Sheet 1 General Description The AS1352 is a high-performance quad CMOS lowdropout voltage regulator in a single 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 allows for fast prototyping reducing development times and costs significant. Factory trimmed versions for full-production are also available. Stability is guaranteed with ceramic 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 condition...
