MAX882ESA+T

The MAX882ESA+T 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 1.5W package allows wider operating range for input voltage and output current. The MAX882 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 MAX882 features a 7μA standby mode that disables output but keeps reference, low battery comparator and biasing circuitry alive. The output is preset at 3.3V and also employs Dual Mode operation allowing user adjustable outputs from 1.25V to 11V using external resistors.
