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.
