PRELIMINARY INFORMATION  
TC1054  
50mA CMOS LDO WITH SHUTDOWN AND ERROR OUTPUT  
GENERAL DESCRIPTION  
FEATURES  
TheTC1054isahighaccuracy(typically±0.5%)CMOS  
upgrade for older (bipolar) low dropout regulators. De-  
signed specifically for battery-operated systems, the  
TC1054’s CMOS construction eliminates wasted ground  
current, significantly extending battery life. Total supply  
current is typically 50µA at full load (20 to 60 times lower  
than in bipolar regulators!).  
TC1054 key features include ultra low noise operation,  
very low dropout voltage (typically 100mV at full load) and  
internal feed-forward compensation for fast response to  
step changes in load. An error output (ERROR) is asserted  
when the TC1054 is out-of-regulation (due to a low input  
voltage or excessive output current). ERROR can be used  
as a low battery warning or as a processor RESET signal  
(withtheadditionofanexternalRCnetwork).Supplycurrent  
is reduced to less than 1µA, and both VOUT and ERROR  
are disabled when the shutdown input is low. The TC1054  
incorporates both over-temperature and over-current pro-  
tection.  
■ Zero Ground Current for Longer Battery Life  
■ Very Low Dropout Voltage  
■ Guaranteed 50mA Output  
■ High Output Voltage Accuracy  
■ Standard or Custom Output Voltages  
■ Power-Saving Shutdown Mode  
■ ERROR Output can be Used as a Low Battery  
Detector, or Processor Reset Generator  
■ Over-Current and Over-Temperature Protection  
■ Space-Saving SOT-23A-5 Package  
■ Pin Compatible Upgrades for Bipolar Regulators  
APPLICATIONS  
■ Battery Operated Systems  
■ Portable Computers  
■ Medical Instruments  
■ Instrumentation  
■ Cellular/GSMS/PHS Phones  
■ Linear Post-Regulators for SMPS  
■ Pagers  
The TC1054 is stable with an output capacitor of only  
1µF and has a maximum output current of 50mA. For higher  
output current regulators, please see the TC1055  
(IOUT = 100mA) regulator and TC1107, TC1108 (IOUT  
300mA) data sheets.
