MC34268数据手册集成电路（IC）的特殊用途稳压器规格书PDF

描述 Description

The MC34268 is a medium current, low dropout (LDO) positive linear 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 linear voltage regulator consists of a 1.0 V dropout composite PNP/NPN pass transistor, current limiting, and thermal limiting. This LDO is packaged in the SOIC-8 and DPAK-3 surface mount power packages. Applications include active SCSI-2 terminators and post regulation of switching power supplies.
