Bypass  
REF  
Features  
General Description  
• Extremely Low Supply Current (50µA, Typ.)  
• Very Low Dropout Voltage  
The TC1174 is an adjustable output CMOS low dropout  
regulator. Total supply current is typically 50µA at full  
load (20 to 60 times lower than in bipolar regulators).  
• 300mA Output Current  
TC1174 key features include ultra low noise operation  
(plus optional Bypass input); very low dropout voltage  
(typically 270mV at full load) and internal feed-forward  
compensation for fast response to step changes in  
load. Supply current is reduced to 0.05µA (typical) and  
• Adjustable Output Voltages  
• Power Saving Shutdown Mode  
• Bypass Input for Ultra Quiet Operation  
• Over Current and Over Temperature Protection  
• Space-Saving MSOP Package Option  
V
falls to zero when the shutdown input is low.  
OUT  
The TC1174 incorporates both over temperature and  
over current protection. The TC1174 is stable with an  
output capacitor of only 1µF and has a maximum  
output current of 300mA.
