Ultra-low quiescent-current regulator suits IoT SoCs at 55nm
Since they use just 1% of their battery life in active mode, one of the major challenges of IoT applications is lowering the deep-sleep mode power consumption. Designers need to achieve a power consumption as low as a few micro-amps, while preserving data retention and supplying always-on functions. The qLR-Aubrey ultra-low quiescent-current linear regulator from Dolphin Integration meets this need.
Featuring 150nA quiescent current and driving up to 1mA, the qLR-Aubrey regulator is an essential component enabling system architects to take benefit of the lowest retention voltage for their power island, as low as 0.55V, while ensuring an efficient voltage regulation of logic in retention.
The qLR-Aubrey enhances the overall performance of a Retention Alternating Regulator (RAR). The RAR features the benefit of the qLR-Aubrey for retention mode, while supporting a load with high-current through its switching regulator during active mode. Mode transitions are ensured by the embedded Regulator Control Unit, which enables safe transitions between the low-power and normal modes.
Overall our users can benefit from our encompassing low-power libraries, which features low-voltage capabilities for retention of main-stem islands and for always-on islands, operating down to 0.55V, thus allowing an additional progress toward power reduction.
