The MAX883CSA+ is a low IQ, low dropout linear regulator in 8 pin NSOIC package. It maximizes battery life by combining ultra low supply currents and low dropout voltages. It has 200mA output current capability at up to +125°C junction temperature. The MAX883 uses P-channel MOSFET pass transistor to maintain low 11µA (15µA maximum) supply current from no load to the full 200mA output. Unlike earlier bipolar regulators, there are no PNP base current losses that increase with output current. In dropout, the MOSFET does not suffer from excessive base currents that occur when PNP transistors go into saturation. The MAX883 features shutdown (OFF) mode that turns off all circuitry by reducing supply current to less than 1µA. This device includes low battery detection comparator, foldback current limiting, reverse current protection and thermal overload protection.
