NCP4686 400 mA, High Accuracy, Low Input Voltage, Low Dropout Regulator The NCP4686 is CMOS Linear voltage regulators with 400 mA output current capability. The device has very high output voltage accuracy, low supply current and low ON−resistance transistor. The NCP4686 is easy to use and includes output current fold−back protection and a fully integrated constant slope circuit as a soft−start circuit. Due to it inrush current is minimized and no output voltage overshoots are there. A Chip Enable function is included to save power by lowering supply current.

NCP4686x VIN VIN VOUT VOUT CE C1 1m also prevents overshoot of the output voltage at start up. The Constant slope circuit is fully built in and no external component is needed. Since the Start up time and output voltage slope is defined internally, there is no way to change it. Starting up into bigger output capacitors doesn’t cause problems due to the combination of the constant slope and current limit circuits. C2 1m GND Current Limit This regulator includes fold−back type current limit circuit. This type of protection doesn’t limit current up to current capability in normal operation, but when over current occurs, the output voltage and current decrease until the over current condition ends. Typical characteristics of this protection type can be observed in the Output Voltage versus Output Current graphs shown in the typical characteristics chapter of this datasheet. Figure 45. Typical Application Schematics Input Decoupling Capacitor (C1) A 1 mF ceramic input decoupling capacitor should be connected as close as possible to the input and ground pin of the NCP4686. Higher values and lower ESR improves line transient response. Output Discharger The NCP4686D version 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. Output Decoupling Capacitor (C2) A 1 mF ceramic output decoupling capacitor is enough to achieve stable operation of the IC. If a tantalum capacitor is used, and its ESR is high, loop oscillation may result. The capacitors should be connected as close as possible to the output and ground pins. Larger values and lower ESR improves dynamic parameters. Thermal As 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. 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. The enable pin has an internal pull down current source. If the enable function is not needed connect CE pin to VIN. PCB Layout Make the VIN and GND line as large as practical. 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. Constant Slope Circuit The constant slope circuit is used as a soft start circuit that allows the output voltage to start up slowly with a defined slope. This circuit minimizes inrush current at start up and ORDERING INFORMATION Device Nominal Output Voltage Description Marking Package Shipping† NCP4686DSN08T1G 0.8 V Auto discharge CAB SOT23−5 (Pb−Free) 3000 / Tape & Reel NCP4686DSN10T1G 1.0 V Auto discharge CAD SOT23−5 (Pb−Free) 3000 / Tape & Reel NCP4686DSN12T1G 1.2 V Auto discharge CAF SOT23−5 (Pb−Free) 3000 / Tape & Reel NCP4686DSN18T1G 1.8 V Auto discharge CAM SOT23−5 (Pb−Free) 3000 / Tape & Reel †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. *To order other package and voltage variants, please contact your ON Semiconductor sales representative. http://onsemi.com 14 NCP4686 PACKAGE DIMENSIONS SC−88A (SC−70−5/SOT−353) CASE 419A−02 ISSUE K A NOTES: 1.
