TC1267 Overview
The TC1267 is an application-specific, low dropout regulator (LDO), specifically intended for use in PCI peripheral card applications plying with PCI Power Management (PCI 2.0). It provides an uninterrupted, 3.3V output voltage when the main (5V) or auxiliary (3.3V) input voltage supplies are present. The TC1267 consists of an LDO, a voltage threshold detector, external switchover logic and gate drive circuitry.
