TC1300  
300 mA CMOS LDO with Shutdown, Bypass and  
Independent Delayed Reset Function  
Features  
General Description  
• LDO with Integrated Microcontroller Reset  
Monitor Functionality  
The TC1300 combines a low dropout regulator and a  
microcontroller reset monitor in an 8-Pin MSOP pack-  
age. Total supply current is 80 µA (typical), 20 to 60  
times lower than bipolar regulators.  
• Low Input Supply Current (80 µA, typical)  
• Very Low Dropout Voltage  
The TC1300 has a precise output with a typical accu-  
racy of ±0.5%. Other key features include low noise  
operation, low dropout voltage and internal feed-  
forward compensation for fast response to step  
changes in load. The TC1300 has both over-tempera-  
ture and over-current protection. When the shutdown  
control (SHDN) is low, the regulator output voltage falls  
to zero, RESET output remains valid and supply cur-  
rent is reduced to 30 µA (typical). The TC1300 is rated  
for 300 mA of output current and stable with a 1 µF out-  
put capacitor.  
• 10 µsec (typ.) Wake-Up Time from SHDN  
• 300 mA Output Current  
• Standard or Custom Output and Detected  
Voltages  
• Power-Saving Shutdown Mode  
• Bypass Input for Quiet Operation  
• Separate Input for Detected Voltage  
• 140 msec Minimum RESET Output Duration  
• Space-Saving MSOP Package  
• Specified Junction Temperature Range:  
-40°C to +125°C  
An active-low RESET is asserted when the detected  
voltage (VDET) falls below the reset voltage threshold.  
The RESET output remains low for 300 msec (typical)  
after VDET rises above reset threshold. The TC1300  
also has a fast wake-up response time (10 µsec.,  
typical) when released from shutdown.  
Applications  
• Battery-Operated Systems  
• Portable Computers  
• Medical Instruments  
• Pagers  
• Cellular / GSM / PHS Phones
