SPX1117 SPX1117 880000mmAA LLooww DDrrooppoouutt VVoollttaaggee RReegguullaattoorr September 2018 Rev. 2.1.1 GENERAL DESCRIPTION APPLICATIONS The SPX1117 is a low power positive-voltage Desktop PC Servers regulator designed to satisfy moderate power Graphic/Video Cards requirements with a cost effective, small footprint solution. Industrial Equipments This device is an excellent choice for use in Power Supplies battery-powered applications and portable computers. The SPX1117 features very low FEATURES quiescent current and a low dropout voltage of 1.1V at a full load. As output current Guaranteed 800mA Output Current decreases, quiescent current flows into the Guaranteed 1A Peak Current load, increasing efficiency. SPX1117 is available in adjustable or fixed 1.5V, 1.8V, Three Terminal Adjustable or Fixed 2.5V, 3.3V and 5V output voltages. 1.5V, 1.8V, 2.5V, 3.3V and 5V The SPX1117 is offered in a 3-pin SOT-223 Low Quiescent Current surface mount packages. Low Dropout Voltage of 1.1V at 800mA An output capacitor of 10F provides 0.1% Line and 0.2% Load Regulation unconditional stability while a smaller 2.2F capacitor is sufficient for most applications. Stable with 2.2F Ceramic Capacitor Overcurrent and Thermal Protection Lead Free, RoHS Compliant SOT223 Package FUNCTIONAL DIAGRAM Fig. 1: SPX1117 Application Diagram 1/11 Rev. 2.1.1 SPX1117 SPX1117 880000mmAA LLooww DDrrooppoouutt VVoollttaaggee RReegguullaattoorr ABSOLUTE MAXIMUM RATINGS These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied.
