TC1174  
300mA Adjustable CMOS LDO with Shutdown and VREF Bypass  
GENERAL DESCRIPTION  
FEATURES  
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!).  
Extremely Low Supply Current (50µA, Typ.)  
Very Low Dropout Voltage  
Guaranteed 300mA Output  
TC1174 key features include ultra low noise operation  
(plus optional Bypass input); very low dropout voltage (typi-  
cally 240mV at full load) and internal feed-forward compen-  
sation for fast response to step changes in load. Supply  
current is reduced to 0.05µA (typical) and VOUT falls to zero  
when the shutdown input is low. 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.
