Austriamicrosystems Introduces 1A Dropout Regulator

Austriamicrosystems has expanded its dropout regulator (LDO) portfolio with the AS1364, delivering up to 1A while operating at lowest dropout voltages. Suited for dual/triple standard-cell and single Li-ion battery powered applications, the Model AS1364 LDO offers dropout voltage of 140 mV at 1 A with quiescent current of 35 µA during operation and 10 nA during shutdown. It is available as adjustable version or with pre-programmed output voltages in range between 1.2-5.0 V with output voltage accuracy of 0.75%. Unit comes in 3 x 3 mm 8-pin package suitable for -40 to +85°C operating environments range. 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.
