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 1V at a full load
and
lower as output current decreases. 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.
