TC1173  
300mA CMOS LDO with Shutdown ERROR Output and Bypass  
Features  
General Description  
• Extremely Low Supply Current for Longer Battery Life  
• Very Low Dropout Voltage  
The TC1173 is a precision output (typically ±0.5%)  
CMOS low dropout regulator. Total supply current is  
typically 50A at full load (20 to 60 times lower than in  
bipolar regulators).  
• 300mA Output Current  
• Standard or Custom Output Voltages  
TC1173 key features include ultra low noise operation  
(plus optional Bypass input); very low dropout voltage  
(typically 240mV at full load) and internal feed-forward  
compensation for fast response to step changes in  
load. An error output (ERROR) is asserted when the  
TC1173 is out-of-regulation (due to a low input voltage  
or excessive output current). ERROR can be set as a  
low battery warning or as a processor RESET signal  
(with the addition of an external RC network). Supply  
current is reduced to 0.05A (typical) and VOUT and  
ERROR fall to zero when the shutdown input is low.  
• ERROR Output Can Be Used as a Low Battery  
Detector or Processor Reset Generator  
• Power Saving Shutdown Mode  
• Bypass Input for Ultra Quiet Operation  
• Over Current and Over Temperature Protection  
• Space-Saving MSOP Package Option  
Applications  
• Battery Operated Systems  
• Portable Computers  
• Medical Instruments  
• Instrumentation  
The TC1173 incorporates both over temperature and  
over current protection. The TC1173 is stable with an  
output capacitor of only 1F and has a maximum  
output current of 300mA.  
• Cellular/GSM/PHS Phones  
• Linear Post-Regulators for SMPS  
• Pagers
