TC1263  
500 mA, Fixed-Output, CMOS LDO with Shutdown  
Features  
Description  
• Very Low Dropout Voltage  
The TC1263 is a fixed-output, high-accuracy (typically  
±0.5%) CMOS low dropout regulator. Designed  
specifically for battery-operated systems, the TC1263’s  
CMOS construction eliminates wasted ground current,  
significantly extending battery life. Total supply current  
is typically 80 µA at full load (20 to 60 times lower than  
in bipolar regulators).  
• 500 mA Output Current  
• High-Output Voltage Accuracy  
• Standard or Custom Output Voltages  
• Overcurrent and Overtemperature Protection  
• SHDN Input for Active Power Management  
• ERROR Output Can Be Used as a Low Battery  
Detector (SOIC only)  
TC1263 key features include ultra low noise operation,  
very low dropout voltage (typically 350 mV at full load)  
and fast response to step changes in load.  
Applications  
The TC1263 incorporates both overtemperature and  
overcurrent protection. The TC1263 is stable with an  
output capacitor of only 1 µF and has a maximum  
output current of 500 mA. It is available in 8-Pin SOIC,  
5-Pin TO-220 and 5-Pin DDPAK packages.  
• Battery-Operated Systems  
• Portable Computers  
• Medical Instruments  
• Instrumentation  
• Cellular/GSM/PHS Phones  
• Linear Post-Regulators for SMPS  
• Pagers
