Product Details
The MAX882 features a 7µA standby mode that disables the output but keeps the reference, low-battery comparator, and biasing circuitry alive. The MAX883/MAX884 feature a shutdown (OFF) mode that turns off all circuitry, reducing supply current to less than 1µA. All three devices include a low-battery-detection comparator, fold-back current limiting, reverse-current protection, and thermal-overload protection.
The output is preset at 3.3V for the MAX882/MAX884 and 5V for the MAX883. In addition, all devices employ 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.
For low-dropout linear regulators with output currents up to 500mA, refer to the MAX603/MAX604 data sheet.
