TC1268  
500mA Fixed Output, Fast Response CMOS LDO with Shutdown  
Features  
General Description  
• Very Low Dropout Voltage  
The TC1268 is a fixed output, fast turn-on, high  
accuracy (typically ±0.5%) CMOS low dropout  
regulator. Designed specifically for battery-operated  
systems, the TC1268’s CMOS construction eliminates  
wasted ground current, significantly extending battery  
life. Total supply current is typically 80µA at full load (20  
to 60 times lower than in bipolar regulators).  
• 500mA Output Current  
• High Output Voltage Accuracy  
• Standard or Custom Output Voltages  
• Over Current and Over Temperature Protection  
• SHDN Input for Active Power Management  
• ERROR Output to Detect Low Battery  
• 5µsec (typical) Wake-up Time from SHDN  
TC1268’s key features include ultra low noise, very low  
dropout voltage (typically 350mV at full load), and  
fast response to step changes in load. The TC1268  
also has a fast wake-up response time (5µsec typically)  
when released from shutdown. The TC1268  
incorporates both over temperature and over current  
protection. The TC1268 is stable with an output  
capacitor of only 1µF and has a maximum output  
current of 500mA.  
Applications  
• RAMBUS Memory Module  
• Battery-Operated Systems  
• Portable Computers  
• Medical Instruments  
• Instrumentation  
Typical Application  
• Cellular/GSM/PHS Phones  
• Linear Post-Regulator for SMPS  
• Pagers
