The MAX667 low-dropout, posiTIve, linear voltage regulatorsupplies up to 250mA of output current. With noload, it has a typical quiescent current of 20μA. At200mA of output current, the input/output voltage differenTIalis typically 150mV. Other features include a lowvoltagedetector to indicate power failure, as well asearly-warning and low-dropout detectors to indicate animminent loss of output voltage regulaTIon. A shutdowncontrol disables the output and puts the circuit into alow quiescent-current mode.The MAX667 employs Dual Mode™ operaTIon. Onemode uses internally trimmed feedback resistors to produce+5V. In the other mode, the output may be variedfrom +1.3V to +16V by connecting two external resistors.The MAX667 is a pin-compatible upgrade to theMAX666 in most applications where the input voltagesare above +3.5V. Choose the MAX667 when high outputcurrents and/or low dropout voltages are desired,as well as for improved performance at highertemperatures.________________________ApplicationsBattery-Powered DevicesPagers and Radio Control ReceiversPortable InstrumentsSolar-Powered Instruments
