Product Summary

The MAX603ESA+T low-dropout, low quiescent current, linear regulator supplies 5V, 3.3V, or an adjustable output for currents up to 500mA. The MAX603ESA+T is available in a 1.8W SO package. Typical dropouts are 320mV at 5V and 500mA, or 240mV at 3.3V and 200mA. Quiescent currents are 15μA typ and 35μA max. Shutdown turns off all circuitry and puts the regulator in a 2μA off mode. A unique protection scheme limits reverse currents when the input voltage falls below the output. Other features include foldback current limiting and thermal overload protection. The output is preset at 5V for the MAX603ESA+T. In addition, The MAX603ESA+T employs Dual Mode. operation, allowing user-adjustable outputs from 1.25V to 11V using external resistors. The input voltage supply range is 2.7V to 11.5V.
