LT1118/LT1118-2.5/LT1118-2.85/LT1118-5 - Low IQ, Low Dropout, 800mA, Source and Sink Regulators Adjustable and Fixed 2.5V, 2.85V, 5V Output
DESCRIPTION Low IQ, Low Dropout, 800mA, Source and SinkRegulators Adjustable andFixed 2.5V, 2.85V, 5V OutputThe LT1118 family of low dropout regulators has the unique capability of maintaining output regulation while sourcing or sinking load current. The 2.85V output voltage regulator 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 600A, allowing continu-ous connection to the TERMPWR lines. An ultralow power shutdown mode is also available on the SO-8 version. In Shutdown the output is high impedance and supply cur-rent drops to less than 10A.Current limits in both sourcing and sinking modes, plus on-chip thermal shutdown make the circuit tolerant of output fault conditions FEATURES APPLICATIONS nRegulates While Sourcing or Sinking CurrentProvides Termination for up to 27 SCSI Lines600A Quiescent CurrentLOAD 0.22F Computersn Disk Drivesn CD-ROMn Supply SplitterLT1118-2.85GND1118 TA01IN2.2F5V1F CERAMICILOADOUT0V-0.2V800mA0mA-400mA1118 TA02VOUTILOADLT1118/LT1118-2.5/LT1118-2.85/LT1118-521118fd ABSOLUTE MAXIMUM RATINGSSupply Voltage (VCC) 15VInput Voltage (Enable)-0.2V to 7VOutput Voltage .-0.2V to VCC + 0.5VShort-Circuit Duration .Inde nite(Note 1)2348765S8 PACKAGE8-LEAD PLASTIC SOINOUTINGNDNCENFBJMAX = 125C, JA = 15C/W2348765S8 PACKAGE8-LEAD PLASTIC SOGNDGNDNCINOUTGNDINJMAX = 125C, JA = 15C/W21TAB ISGNDINGNDOUTST PACKAGE3-LEAD PLASTIC SOT-223JMAX = 125C, JC = 15C/W PIN CONFIGURATIONORDER INFORMATIONLEAD FREE FINISHTAPE AND REELPART MARKINGPACKAGE DESCRIPTIONTEMPERATURE RANGELT1118CS8#PBFLT1118CS8#TRPBF11188-Lead Plastic SO0C to 70CLT1118CS8-2.5#PBFLT1118CS8-2.5#TRPBF1118258-Lead Plastic SO0C to 70CLT1118CS8-2.85#PBFLT1118CS8-2.85#TRPBF1118288-Lead Plastic LT1118/LT1118-2.5LT1118-2.85/LT1118-511118fd T
