TC1267 400mA PCI LDO Features • • • • • • • • Glitch Free Transition Between Input Sources Automatic Input Source Selection External PMOS Bypass Switch Control Built-in 5V Detector 1% Regulated Output Voltage Accuracy 400mA Load Current Capability Kelvin Sense Input Low Ground Current, Independent of Load General Description The TC1267 is an application-specific, low dropout regulator (LDO), specifically intended for use in PCI peripheral card applications complying 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.
