UC560  
27-Line SCSI Source/Sink Regulator  
FEATURES  
DESCRIPTION  
Complies with SCSI, SCSI-2, SCSI-3  
SPI and Ultra SCSI (Fast-20)  
The UC560 provides current for up to 27 lines of active termination for a  
SCSI (Small Computers Systems Interface) parallel bus. The SCSI  
standard requires active termination at both ends of the cable. The  
UC560 is based on the UC5603 and UC5613 SCSI Active Terminators.  
It uses the voltage regulator and internal logic circuits of those parts,  
but has no termination circuits. The UC560 provides greater source cur-  
rent drive capability compared to the UC5603 and UC5613.  
2.85V Regulated Output Voltage With  
1.4% Tolerance  
Provides Current for up to 27 Lines of  
Active Termination for SCSI Buses  
• −750mA Sourcing Current for  
Termination  
The UC560 sink current maintains regulation with all active-negation  
drivers negated. It provides a disconnect feature which disables the  
regulator to greatly reduce standby power. Internal circuit trimming is  
utilized for a 1.4% tolerance output voltage. Other features include ther-  
mal shutdown and current limit for short circuit conditions.  
+300mA Sinking Current for Active  
Negation Drivers  
0.9V Dropout Voltage Regulator at  
750mA and 2.75V Output  
The UC560 is available in low thermal resistance versions of the indus-  
try standard 8-pin power SOIC, 5-pin TO-220 and 5-pin TO-263.
