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.

• 100µA Supply Current in Disconnect

Mode

• Current Limit and Thermal Shutdown

Protection

• Low Thermal Resistance Surface Mount
