If the enable function is not needed connect CE pin to VIN. The D version of the NCP4687 device includes a transistor between VOUT and GND that is used for faster discharging of the output capacitor. This function is activated when the IC goes into disable mode. A typical application circuit for NCP4687 series is shown in the Figure 39. NCP4687x VIN SENSE CE C1 1.0 mF VOUT VOUT VIN GND C2 1.0 mF Thermal Consideration 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 165°C. After that, when junction temperature decreases below 100°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. Figure 39. Typical Application Schematic Input Decoupling Capacitor (C1) A 1.0 mF ceramic input decoupling capacitor should be connected as close as possible to the input and ground pin of the NCP4687 device. Higher values and lower ESR improves line transient response. Output Decoupling Capacitor (C2) A 1.0 mF ceramic output decoupling capacitor is sufficient to achieve stable operation of the device. If tantalum capacitor is used, and its ESR is high, the loop oscillation may result. The capacitor should be connected as close as possible to the output and ground pin. Larger values and lower ESR improves dynamic parameters. Sense Pin The SENSE pin improves significantly the load regulation. The connection resistance between the LDO and the load given by PCB parameters has reduced impact to load regulation. If possible, use wide PCB traces as short as possible. Enable Operation The enable pin CE may be used for turning the regulator on and off. The IC is switched on when a high level voltage is applied to the CE pin.
