General Description

The MAX8862 low-cost, low-dropout, dual linear voltage regulator is ideal for battery-powered and portable applications. The regulators have independent supply inputs and provide 250mA and 100mA, respectively, with a full-load dropout voltage of 160mV. Both regulators use P-channel MOSFET pass transistors and maintain low quiescent current independent of load current. In dropout, the MOSFET does not suffer from excessive base currents, as do saturated PNP transistors.
