Extended battery life in portable devices with new low Iq LDO
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 MCP1811...
