TC1173  
300mA CMOS LDO with Shutdown, ERROR Output and Bypass  
GENERAL DESCRIPTION  
FEATURES  
The TC1173 is a precision output (typically ±0.5%)  
CMOS low dropout regulator. Total supply current is typi-  
cally 50µA at full load (20 to 60 times lower than in bipolar  
regulators!).  
Extremely Low Supply Current for Longer  
Battery Life!  
Very Low Dropout Voltage  
300mA Output  
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 0.05µA (typical)  
and VOUT and ERROR fall to zero when the shutdown input  
is low.  
Standard or Custom Output Voltages  
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  
Cellular / GSM / PHS Phones  
Linear Post-Regulator for SMPS  
Pagers  
The TC1173 incorporates both over-temperature and  
over-currentprotection.TheTC1173isstablewithanoutput  
capacitor of only 1µF and has a maximum output current of  
300mA.
