Austriamicrosystems, a designer and manufacturer of analog integrated circuits, has announced the expansion of its low dropout regulator portfolio with the AS1358/59/61/62 family optimized to deliver outstanding noise performance of less than 9uVRMS and up to 92dB PSRR.
The AS1358/59/61/62 family, operating from a 2 to 5.5V supply, is the perfect low dropout regulator (LDO) for dual or triple standard-cell and single Li-Ion battery-powered applications, the company claims. With a low dropout voltage of 70mV typ @ 150mA and 140mV typ @ 300mA (AS1359/62 only) at an extremely low current of only 40uA typ during operation and 9nA typ during shutdown, battery lifetime can be maximized using these new ultra-low-noise integrated circuits (ICs).
The AS1358/59/61/62 family offers pre-programmed output voltages in the range of 1.4 to 4.5V with an output voltage accuracy of 1% (@ 300mA). An additional feature of the AS1361/62 is a power-ok output that signals when the output voltage drops out of regulation.
Walter Moshammer, marketing director Standard Linear at Austriamicrosystems, said: AS1358/59/61/62 are the LDOs of choice for powering circuits that require a low-noise supply, such as RF, cell-phone cameras, wireless base stations and PA bias supplies. Offering low dropout voltage as well as low quiescent current, this ultra-low-noise LDO family is ideally suited for any battery-powered device.
