Product Summary

The MAX1806EUA33 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 MAX1806EUA33 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 MAX1806EUA33 include Notebook Computers, Cellular and Cordless Telephones, PDAs, Palmtop Computers, Base Stations, USB Hubs, Docking Stations.
