The MAX8865TEUA+ is a low cost, dual, low dropout linear regulator in 8 μMAX package. The device operates from 2.5V to 5.5V input range and delivers up to 100mA output current. At 200mA total load, the PMOS pass transistors keep the supply current at 145μA which makes this device as an ideal device for battery operated equipments. The MAX8865T has Dual Mode operation with output voltage preset at 3.15V and can be adjusted with external resistor dividers. The device is featured with independent low power shutdown, short circuit protection, thermal shutdown protection and reverse battery protection. It has 1.25V reference and two independent linear regulators. Each linear regulator consists of an error amplifier, MOSFET driver, P-channel pass transistor, Dual Mode comparator and internal feedback voltage divider.
