MAX1818 500mA Low-Dropout Linear Regulator in SOT23 General Description Features
The MAX1818 low-dropout linear regulator operates ● Guaranteed 500mA Output Current from a +2.5V to +5.5V supply and delivers a guaranteed ● Low 120mV Dropout at 500mA 500mA load current with low 120mV dropout. The high- accuracy (±1%) output voltage is preset at an internally ● ±1% Output Voltage Accuracy trimmed voltage (see Selector Guide) or can be adjusted • Preset at 1.5V, 1.8V, 2.0V, 2.5V, 3.3V, 5V from 1.25V to 5.0V with an external resistive divider. • Adjustable from 1.25V to 5.0V An internal PMOS pass transistor allows the low 125μA ● Power OK Output supply current to remain independent of load, making this ● Low 125μA Ground Current device ideal for portable battery-operated equipment such ● 0.1μA Shutdown Current as personal digital assistants (PDAs), cellular phones, cordless phones, base stations, and notebook computers. ● Thermal Overload Protection Other features include an active-low open-drain reset ● Output Current Limit output that indicates when the output is out of regulation, ● Tiny 800mW 6-Pin SOT23 Package a 0.1μA shutdown, short-circuit protection, and thermal shutdown protection. The device is available in a minia- ture 800mW 6-pin SOT23 package.
