TC1266  
200mA PCI LDO  
Features  
General Description  
• Glitch Free Transition Between Input Sources  
• Automatic Input Source Selection  
• External PMOS Bypass Switch Control  
• Built-in 5V Detector  
The TC1266 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, 200mA (max) output voltage when the main (5V)  
or auxiliary (3.3V) input voltage supplies are present.  
• 1% Regulated Output Voltage Accuracy  
• 200mA Load Current Capability  
• Kelvin Sense Input  
The TC1266 consists of an LDO, a voltage threshold  
detector, external switchover logic and gate drive  
circuitry. It functions as a conventional LDO as long as  
• Low Dropout Voltage (240mV @ Full Load)  
• Low Ground Current, Independent of Load  
the voltage on the main supply input (V ) is above the  
IN  
lower threshold (3.90V typical). Should the voltage on  
V
fall below the lower threshold, the LDO is disabled  
Applications  
IN  
and an external P-channel MOSFET is automatically  
turned on, connecting the auxiliary supply input to  
• PCMCIA  
• PCI  
V
and ensuring an uninterrupted 3.3V output. The  
OUT,  
• Network Interface Cards (NICs)  
• CardbusTM Technology  
main supply is automatically selected, if both the main  
and auxiliary input supplies are present, and transition  
from one input supply to the other is ensured glitch-  
free. High integration, automatic secondary supply  
switchover, Kelvin sensing, and small size make the  
TC1266 the optimum LDO for PCI 2.0 applications.
