800mA Low Dropout Regulator
SCSI-II Active Terminator
CORPORATION
CLM1117
FEATURES
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 choice for use in battery-
powered 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 regulator circuits.
