NCP4672

Dual Linear Voltage

Regulators with V_inand V_out

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.
