austriamicrosystems Introduces New Dual Ultra Low Voltage Noise LDO with Excellent Power Supply Rejection Ratio

The dual low drop out regulator AS1374 is ideally suited for a wide range of
portable battery powered devices. The low noise and excellent PSSR enable radio
designers to achieve optimum system performance.
UNTERPREMSTAETTEN, Austria--(Business Wire)--
austriamicrosystems (SIX:AMS), a leading global designer and manufacturer of
high performance analog ICs for communications, industrial, medical and
automotive applications expanded its low dropout regulator portfolio with the
dual LDO AS1374, capable of delivering up to 200mA continuous load current at
each output.

"AS1374 is the dual low drop out regulator of choice for powering circuits that
require a low-noise supply, such as RF, cell-phone cameras, wireless base
stations and PA bias supplies. Its` superior performance in radio based designs
provides the engineers much needed design margin while maintaining the overall
system integrity", said Bruce Ulrich, marketing director Consumer &
Communications at austriamicrosystems. "Offering low dropout voltage as well as
low quiescent current, this dual ultra low voltage noise LDO is ideally suited
for any battery-powered device and complements our family of ultra low noise
LDO`s."

austriamicrosystems` AS1374 operates from a 2 to 5.5V supply, making it ideal
for portable battery powered applications. Offering low 120mV dropout at 200mA
load currents at each output, it has been designed and optimized to work with
low-cost, small-capacitance ceramic capacitors. The AS1374 is available with
pre-programmed output voltages between 1.2V and 3.6V (programmable in 50mV
steps). The device uses an advanced architecture to achieve ultra low output
voltage noise of 20uVRMS and a power supply rejection ratio of better than 85dB
(@ 1kHz). Two active-high enable pins allow the possibility to switch on or off
each output independently from each other.

The AS1374 requires only 1uF output capacitor for stability at any load. The
device is available in a 6-bump WLP package. For further information about the
features of this ultra low voltage noise low drop out regulator AS1374 please
