TC1107  
300mA CMOS LDO with Shutdown and VREF Bypass  
Features  
General Description  
• Extremely Low Supply Current (50A, Typ.)  
• Very Low Dropout Voltage  
The TC1107 is a fixed output, high accuracy (typically  
±0.5%) CMOS upgrade for older (bipolar) low dropout  
regulators. Total supply current is typically 50A at full  
load (20 to 60 times lower than in bipolar regulators).  
• 300mA Output Current  
• High Output Voltage Accuracy  
TC1107 key features include ultra low noise operation  
(plus optional Bypass input); very low dropout voltage  
(typically 240mV at full load), and fast response to step  
changes in load. Supply current is reduced to 0.05A  
(typical) and VOUT falls to zero when the shutdown  
input is low.  
• 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 Option  
The TC1107 incorporates both over temperature and  
over current protection. The TC1107 is stable with an  
output capacitor of only 1F and has a maximum  
output current of 300mA.
