The AS1355 300mA triple low drop out regulator (LDO) is ideally suited for both DC-DC regulation, multiple cell or Lithium battery powered devices.
austriamicrosystems (SIX: AMS), a leading global designer and manufacturer of high performance analog ICs for communications, industrial, medical and automotive applications has expanded its low drop out regulator portfolio with the AS1355 triple LDO, capable of delivering up to 300mA at its regulated outputs.
“austriamicrosystems’ AS1355 LDO provides an ultra compact solution for multiple and variable voltage loads” said
Bruce Ulrich, Marketing Director Consumer & Communications at austriamicrosystems. “In many applications both
from an unregulated DC-DC source and batteries, multiple non standard point of load (POL) voltages are becoming
more common. The AS1355 LDO takes advantage of austriamicrosystems Final Test Trim (FTT) capability
enabling customers to realize either samples or production quantities of non standard output voltages within two
weeks. At $0.42 for 1K* pcs the AS1355 is a superb addition to our new ‘Performance without the Premium’ range
of LDO’s.”
The AS1355 low dropout linear regulators 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 portable devices as well as for distributed power circuits. Stability is guaranteed with
ceramic output capacitors of only 1?F. The low equivalent series resistance (ESR) of these capacitors 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 networks. AS1355 triple linear regulator is available in a 16-pin QFN 3 X 3 package.
