Data Sheet
1 General Description
The AS1357 is a high-performance triple CMOS low-
dropout voltage regulator in a single QFN package. The
efficient set of programmable power supplies is opti-
mized to deliver the best compromise between quies-
cent 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 pro-
gramming of the output voltage for each regulator on-
site. The OTP function allows for fast prototyping reduc-
ing 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 capaci-
tors ensures low output impedance at high frequencies.
Regulation performance is excellent even under low
dropout conditions, when the power transistor has to
operate in linear mode.
The low-noise performance allows direct connection of
noise sensitive circuits without additional filtering net-
works.
The AS1357 is available in a 12-pin QFN 4x4 or 16-pin
QFN 3x3 package.
