NCP4672  
Dual Linear Voltage  
Regulators with Vin and Vout  
Voltage Detector  
The NCP4672 is a dual linear voltage regulator with input voltage  
and output voltage detectors. This part is useful in systems where  
multiple voltages are required such as for core and I/O. The NCP4672  
is very accurate at 2% over full input voltage and full load current. The  
NCP4672 eliminates the need for external voltage supervision due to  
the two built in voltage detectors. The voltage detector on the input is  
set to 7.0 V. The output voltage detector is for channel 1 and is set to  
2.9 V. An external capacitor is used to set the duration of this reset  
signal. Other features include short circuit protection and thermal  
shutdown protection. The NCP4672 has been designed to work with a  
4.7 mF output capacitor having an ESR between 0.1 W and 5.0 W.
