PRODUCT DESCRIPTION
The Calogic CLM1117 is a low power positive voltage
regulator designed to meet 800mA output current and comply
with SCSI-II specifications with a fixed output voltage of
2.85V. This device is an excellent choi ce for use i n batterypowered applications, as active terminators for the SCSI bus,
and portable computers. The CLM1117 features very low
quiescent current and very low dropout voltage of 1.2V at a
full load and lower as output current decreases. This product
is available as an adjustable or fixed 2.85V, 3V, 3.3V, and 5V
output voltages.
The device is offered in a 3-pin surface mount package
SOT-223. The output capacitor of 10µF or larger is needed
for output stability of CLM1117 as required by most of the
other regulat or circuits.

Note 1: Output temperature coeffic ien t is define d as the worst case volta ge change divid ed by the total tempe rature range .
Note 2: Dropout voltage is defined as the input to output differential at which the output voltage drops 100mV below its nominal value measured
at 1V differential at very low values of programmed output voltage, the minimum input supply voltage of 2V (2.3V over temperature) must be
taken input account.
Note 3: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied,
excluding load or line regulation effect.
