DESCRIPTION
The LM1117GSF is a low power positive-voltage regulator designed to meet 300mA output current. 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 1.2V at a full load
and lower as output current decreases. LM1117 is available as an adjustable or fixed 1.2V, 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-23.
The output capacitor of 10uF or larger is needed for output stability of LM1117 as required by most of the other
regulator circuits.
