MC34268 Datasheet Scsi-2 ACtive Terminator Regulator

Manufacturer: onsemi

Overview: MC34268 Voltage Regulator - SCSI-2 Active Terminator, Low Dropout 800 mA, 2.85 V 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 posite 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.
