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 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  
lower as output current decreases. LM1117 is available as an adjustable or fixed 1.5V, 1.8V, 2.5V, 2.85V,  
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.
