DESCRIPTION
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 u 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 1V at a full load and lower as output current decreas. LM1117 is available as an adjustable or fixed 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V output voltages.
The LM1117 is offered in a 3-pin surface mount package SOT-223, TO-252 & SOT-89. The output capacitor of 10㎌ or larger is needed for output stability of LM1117 as required by most of the other regulator circuits.
