General Description

The MAX6469–MAX6484 are low-dropout linear regulators with a fully integrated microprocessor reset circuit. Each is available with preset output voltages from +1.5V to +3.3V in 100mV increments and delivers up to 300mA of load current. These devices consume only 82µA of supply current. The low supply current, low dropout voltage, and integrated reset functionality make these devices ideal for battery-powered portable equipment.
