TC1269  
300mA CMOS LDO with Shutdown and VREF Bypass  
FEATURES  
GENERAL DESCRIPTION  
■ Zero Ground Current for Longer Battery Life!  
■ Very Low Dropout Voltage  
■ 300mA Output  
■ High Output Voltage Accuracy  
■ Standard or Custom Output Voltages  
■ Power-Saving Shutdown Mode  
■ Bypass Input for Ultra-Quiet Operation  
■ Over-Current and Over-Temperature Protection  
■ Space-Saving MSOP Package  
The TC1269 is a fixed output, high accuracy (typically  
±0.5%) CMOS upgrade for older (bipolar) low dropout  
regulators. Total supply current is typically 50µA at full load  
(20 to 60 times lower than in bipolar regulators!).  
TC1269 key features include ultra low noise operation  
(plus optional Bypass input); very low dropout voltage (typi-  
cally 240mV at full load), and fast response to step changes  
in load. Supply current is reduced to 0.05µA (typical) and  
V
OUT falls to zero when the shutdown input is low.  
The TC1269 incorporates both over-temperature and  
over-currentprotection. TheTC1269isstablewithanoutput  
capacitor of only 1µF and has a maximum output current of  
300mA.  
APPLICATIONS  
■ Battery-Operated Systems  
■ Portable Computers  
■ Medical Instruments  
■ Instrumentation  
■ Cellular / GSM / PHS Phones  
■ Linear Post-Regulator for SMPS  
■ Pagers
