MC34268/D
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 8–pin SOP–8 and 3–pin DPAK
and SOT–223 surface mount power packages.
Applications include active SCSI–2 terminators and post
regulation of switching power supplies.
