austriamicrosystems Introduces 400mA Low Input Voltage Ultra Low Dropout Regulator

With a Best in Class Minimum Input Voltage of 1.2V, the AS1371 LDO Offers
Battery Life Extension in Many of Today`s Portable Products
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 has expanded its ultra low dropout regulator (LDO)
portfolio with the AS1371; capable of delivering up to 400mA while operating
down to a low input voltage of 1.2V.

The AS1371 operates from a 1.2 to 3.6V supply, making it ideal for low voltage
portable battery powered applications. Offering ultra low dropout voltage of
20mV @ 100mA, 80mV @ 400mA, and with only 50uA quiescent current at maximum
load, the AS1371 helps to maximize battery life and performance.

"As microprocessor core voltages continue to drop, customers need to extend the
longevity of existing Power Management IC`s (PMIC`s)" said Bruce Ulrich,
Marketing Director Consumer & Communications at austriamicrosystems. "Many of
the subsystems in current portable applications such as GPS systems, and
Bluetooth, drive the need for peripheral LDO`s to work in conjunction with an
existing PMIC. The AS1371 addresses this requirement by supporting input
voltages down to 1.2Volts. "

The AS1371 is available with pre-programmed output voltages between 0.6V and
3.3V (programmable in 50mV steps.) The austriamicrosystems solution also
features stable output voltage with ceramic capacitors down to a value of 1uF,
strict output voltage regulation tolerances (+/-1%), and good line- and
load-regulation. The device includes Integrated Overtemperature / Overcurrent
Protection, Under-Voltage Lockout, Power-OK, Low Battery Detection and has a
sense input option.

A digital enabled pin allows system-level dynamic power management. The AS1371
is available in a 6-pin 2x2 TDFN package and is qualified for -40°C to +85°C
operation. For further information about the AS1371low input voltage ultra low
