MC34268 Voltage Regulator - SCSI-2 Active Terminator, Low Dropout

2021-10-13
●The MC34268 is a medium current, low dropout positive voltage regulator specifically designed for use in SCSI−2 active termination circuits. This device offers the circuit designer an economical solution for precision voltage regulation, while keeping power losses to a minimum. The regulator consists of a 1.0 V dropout composite PNP/NPN pass transistor, current limiting, and thermal limiting.These devices are packaged in the SOIC−8 and DPAK−3 and SOT−223 surface mount power packages.
●Applications include active SCSI−2 terminators and post regulation of switching power supplies.
●Features:
■2.85 V Output Voltage for SCSI−2 Active Termination
■1.0 V Dropout
■Output Current in Excess of 800 mA
■Thermal Protection
■Short Circuit Protection
■Output Trimmed to 1.4% Tolerance
■No Minimum Load Required
■Space Saving DPAK−3, SOT−223 and SOIC−8 Surface Mount Power Packages
■Pb−Free Packages are Available
