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.
