austriamicrosystems Introduces 1A Ultra-Low-Dropout Regulator
Operating at lowest dropout voltages, the AS1364 offers excellent 10µVRMS low noise
performance.
Unterpremstaetten, Austria (July 8, 2008) - austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of high performance analog ICs for communications, industrial, medical and automotive applications, today expanded its low dropout regulator (LDO) portfolio with the AS1364, capable of delivering up to 1A while operating at lowest dropout voltages.
The AS1364 operates from a 2 to 5.5V supply, making it ideal for dual or triple standard-cell and single Li-Ion battery powered applications. Offering lowest dropout voltage of 140mV @ 1A with an extremely low quiescent current of only 35µA during operation and stunning 10nA during shutdown, battery life time is maximized when using AS1364.
"There is a growing demand of applications requiring high currents and the need of a LDO smoothed voltage." said Walter Moshammer, Marketing Director Standard Linear at austriamicrosystems. "At currents rated around 1A, the dropout voltage is the most important factor for lifetime and efficiency of the system. austriamicrosystems' AS1364 fulfils these needs completely."
The AS1364 is available as adjustable version or with pre-programmed output voltages in the range between 1.2 to 5.0V with an output voltage accuracy of excellent 0.75%. While the adjustable version allows highest flexibility in design and does not require a bypass capacitance, the pre-programmed versions offer improved noise performance through a bypass pin. The noise is therefore improved from good 50µVrms of the adjustable version to excellent 10µVrms of the pre-programmed versions. Additionally, the AS1364 offers a power-ok output that signals when the output voltage drops out of regulation by 6% typically.
A digital enable pin allows system-level dynamic power management. Furthermore, the AS1364 offers overtemperature and over-current protection. The AS1364 is available in a thermally enhanced TDFN 3x3mm 8-pin package suitable for operating environments ranging from -40 to +85°C.
