1A (Sink & Source) Low Dropout, Low Quiescent Current
Voltage Regulator
POWER MANAGEMENT Description
The SC1118 family of low dropout regulators has the unique capability of maintaining output regulation while sourcing or sinking current.
The 2.
85V output
voltage option is ideal for use as a Boulay termination of up to 27 SCSI data lines.
The regulator maintains regulation while both sourcing and sinking current, enabling the use of active negation drivers for improved noise immunity on the data lines.
Regulation of output
voltage is maintained for TERMPWR
voltages as low as 4.
0V.
When unloaded, quiescent supply current is a low 2mA, allowing continuous connection to the TERMPWR lines.
