The MAX1819 low-dropout linear regulator operates from a 2.5V to 5.5V supply and delivers a guaranteed 500mA load current with low 120mV dropout. The high-accuracy (±1%) output voltage is preset at an internally trimmed voltage (see the Selector Guide in the full data sheet) or can be adjusted from 1.25V to 5V with an external resistive-divider.
An internal PMOS pass transistor allows the low 125µA supply current to remain independent of load, making this device ideal for portable battery-operated equipment such as personal digital assistants (PDAs), cellular phones, cordless phones, base stations, and notebook computers.
Other features include an active-low, open-drain reset output that indicates when the output is out of regulation, a 0.1µA shutdown, short-circuit protection, and thermal shutdown protection. The device is available in a miniature 6-pin UCSP™ package.
