Overview

  • Dual Mode Operation: Fixed +SY or Adjustable from +1.3V to +18V
  • Low Power CMOS: 12,&A Max Quiescent Current
  • 40rnA Output Current, with Current Limiting
  • Pln-Compatlble Upgrade of ICL7883 and ICL7884
  • +2V to +18.SV Operating Range
  • Low Battery Detector (MAX888)
  • No Output Over-Shoot on Power Up

The MAX663/664/666 CMOS voltage regulators have a maximum quiescent current of 12µA. They can be used either as 5 volt, fixed output regulators with no additional components, or can be adjusted from 1.3V to 16V using two external resistors. Fixed or adjustable operation is automatically selected via the VSET input. The MAX66X series, ideally suited for battery powered systems, has an input voltage range of 2 to 16.SV, an output current capability of 40mA, and can operate with low input-output differentials. Other features include current limiting and low power shut down.

The MAX663 positive regulator and MAX664 negative regulator are both pin and electrically compatible with the ICL7663 and ICL7664 and can plug-in replace these devices, improving performance and eliminating the need for external resistors in 5V applications. The MAX666 has a positive output and includes on-chip low-battery detection circuitry.
