NCP4681, NCP4684 150 mA, Ultra Low Quiescent Current, Low Dropout Regulator The NCP4681 and NCP4684 are CMOS Linear voltage regulators with 150 mA output current capability and ultra low supply currents (1 mA typ.) The devices are easy to use and include output current protection and a fully integrated soft−start circuit to minimize inrush current and to ensure no output voltage overshoot. The NCP4681 includes an Enable function to reduce supply current by using a Standby mode, while the NCP4684 excludes the Enable pin to avoid any pull down current, thereby offering the lowest possible current consumption for battery powered applications in Active mode. For portable products the devices are available in the exceptionally small 0.8 x 0.8 mm XDFN, along with the SC−70 and SOT23 packages http://onsemi.com MARKING DIAGRAMS SC−70 CASE 419A XXX XMM 1 Features • • • • • • • • • • • Operating Input Voltage Range: 1.40 V to 5.25 V Output Voltage Range: 0.8 V to 3.6 V (available in 0.1 V steps) Output Voltage Accuracy: ±1.0% Supply Current: 1 mA (excluding the CE pull down current) Dropout Voltage: 0.28 V (IOUT = 150 mA, VOUT = 2.8 V) Line Regulation: 0.02%/V Typ.

A typical application circuits for NCP4681 and NCP4684 series are shown in Figure 41. VIN NCP4681x VIN C1 100n CE Enable Operation (NCP4681 Only) VOUT 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. VOUT GND C2 100n Constant Slope Circuit NCP4684 VIN VIN C1 100n 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 also prevents against overshoot of the output voltage. The Constant slope circuit is fully built in and no external components are needed. Start up time and the output voltage slope is defined internally and there is no way for the user to change it. Start up into bigger output capacitor doesn’t make any problem due to cooperation of constant slope circuit and current limit circuit. VOUT VOUT GND C2 100n Figure 41. Typical Application Schematics Current Limit This regulator includes a fold−back current limiting circuit. This type of protection doesn’t limit output current up to specified current capability in normal operation, but when an over current situation occurs, the output voltage and current decrease until the over current condition ends. Typical characteristics of this protection scheme are shown in the Output voltage versus Output current graphs in the characterization section of this datasheet. Input Decoupling Capacitor (C1) A 0.1 mF ceramic input decoupling capacitor should be connected as close as possible to the input and ground pin of the NCP4681/4. Higher values and lower ESR improves line transient response. Output Decoupling Capacitor (C2) A 0.1 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 http://onsemi.com 14 NCP4681, NCP4684 Output Discharger The NCP4681D 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. 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. Thermal PCB layout 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 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.
