MC34268DR2 Description
The MC34268DR2 is a positive voltage regulator with a medium current and low dropout that was created specifically for SCSI 2 active termination circuits. This component offers the circuit designer a low-cost method for precise voltage regulation while minimizing power losses. A composite PNP/NPN pass transistor with a dropout voltage of 1.0 V, current and thermal limiting, and other components make up the regulator. These components are housed in surface mount power packages such as SOIC8, DPAK3, and SOT223. Active SCSI 2 terminators and switching power supply post regulation are examples of applications.
