DESCRIPTION
(X=Output Voltage=1.5V, 1.8V, 2.5V, 2.85V, '3.0V, 3.3V, 5.0V, Adjustable=AD) The LM1117 is a low power positive-voltage regulator designed to meet 1A output current and comply with SCSI-II specifications with a fixed output voltage of 2.85V. This device is an excellent choice for use in battery-powered applications, as active terminators for the SCSI bus, and portable computers. The LM1117 features very low quiescent current and very low dropout voltage of 700mV at a full load and 3.0V, 3.3V, and 5.0V output voltages. The LM1117 is offered in a 3-pin surface mount package SOT-223 & TO-263. The output capacitor of 10㎌ or larger is needed for output stability of LM1117 as required by most of the other regulator circuits.
