Ultra-low Iq LDO extends battery life in portable devices

October 24, 2018  Stephen Law

MICROCHIP TECHNOLOGY MCP1811 linear Low Dropout (LDO) regulator extends battery life in portable devices up to four times longer than traditional ultra-low quiescent (Iq) LDOs. With an ultra-low Iq of 250 nanoamps (nA) versus the approximately 1uA operation of traditional devices, device reduces quiescent current to save battery life, enabling end users to recharge or replace batteries less often. Ideal for IoT and battery-operated applications such as wearables, remotes and hearing aids, the 250nA ultra-low Iq reduces power consumption in applications by minimizing standby or shutdown current.
