Do not keep CE pin not connected or between VCEH and VCEL voltage levels. Otherwise output voltage would be unstable or indefinite and unexpected would flow internally. A typical application circuit for NCP4641 series is shown in Figure 32. NCP4641x VIN VIN C1 100 n CE VOUT VOUT Thermal As a power across the IC increase, it might become necessary to provide some thermal relief. The maximum power dissipation supported by the device is dependent upon board design and layout. Mounting pad configuration on the PCB, the board material, and also the ambient temperature affect the rate of temperature increase for the part. When the device has good thermal conductivity through the PCB the junction temperature will be relatively low in high power dissipation applications. The IC includes internal thermal shutdown circuit that stops operation of regulator, if junction temperature is higher than 150°C. After that, when junction temperature decreases below 125°C, the operation of voltage regulator would restart. While high power dissipation condition is, the regulator starts and stops repeatedly and protects itself against overheating. C2 100 n GND Figure 32. Typical Application Schematic Input Decoupling Capacitor (C1) The device is stable without any input capacitance, but if input line is long and has high impedance or if more stable operation is needed, input capacitor C1 should be connected as close as possible to the IC. Recommended range of input capacitor value is 100 nF to 10 mF. Output Decoupling Capacitor (C2) PCB Layout The NCP4641 can work stable without output capacitor, but if faster response and higher stability reserve is needed, output capacitor should be connected as close as possible to the device. Recommended range of output capacitance is 100 nF to 10 mF. Larger values of output capacitance and lower ESR improves dynamic parameters. Pins number 2 and 4 of SOT89−5 package and pins number 2, 4 and 5 of SOIC6−TL must be wired to the GND plane while it is mounted on board. Make VIN and GND lines sufficient. If their impedance is high, noise pickup or unstable operation may result. Connect capacitors C1 and C2 as close as possible to the IC, and make wiring as short as possible. Enable Operation The enable pin CE may be used for turning the regulator on and off.
