MIC5204
MIC5204
SCSI-II Active Terminator
Preliminary Information
Micrel
General Description
Features
The MIC5204 is an active terminator designed to comply with • ± 1% output voltage accuracy
SCSI-II specifications. The MIC5204 is enabled by a CMOS • Guaranteed 500mA output
or TTL compatible logic signal. When disabled, power • Low quiescent current
consumption drops nearly to zero and the output goes into a • Low dropout voltage
high impedance state. Key MIC5204 features include protec- • Extremely tight load and line regulation
tion against reversed battery, current limiting, and over- • Very low temperature coefficient
temperature shutdown.
• Current and thermal limiting
• Zero off-mode current
• Logic-controlled electronic shutdown
• Available in SO-8 and SOT-223 packages
