Extending battery life in portable devices up to four times longer than traditional ultra-low quiescent (Iq) LDOs, Microchip has announced a linear Low Dropout (LDO) regulator. With an ultra-low Iq of 250nA versus the approximate 1uA operation of traditional devices, the MCP1811LDO reduces quiescent current to save battery life, enabling end-users to recharge or replace batteries less often. The
