MC34268
800 mA, 2.85 V, SCSI?2
Active Terminator, Low
Dropout Voltage Regulator
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
