Product Summary

The MAX1806EUA15+ is a low-dropout linear regulator operates from a +2.25V to +5.5V supply and delivers a guaranteed 500mA load current with low 175mV dropout. The high-accuracy (±1%) output voltage is preset at an internally trimmed voltage (see Selector Guide) or can be adjusted from +0.8V to +4.5V with an external resistive-divider. An internal PMOS pass transistor allows low 210μA supply current, making the MAX1806EUA15+ ideal for portable equipment such as personal digital assistants (PDAs), cellular phones, cordless phones, and other equipment, including base stations and docking stations. The applications of the MAX1806EUA15+ include Notebook Computers, Cellular and Cordless Telephones, PDAs, Palmtop Computers, Base Stations, USB Hubs, Docking Stations.
