In the disable state the device consumes as low as typ. 10 nA from the VIN. If the EN pin voltage > 0.9 V the device is guaranteed to be enabled. The NCP707 regulates the output voltage and the active discharge transistor is turned*off. The EN pin has an internal pull−down current source with typ. value of 180 nA which assures that the device is turned−off when the EN pin is not connected. A build in 56 mV of hysteresis and deglitch time in the EN block prevents from periodic on/off oscillations that can occur due to noise on EN line. In the case that the EN function isn’t required the EN pin should be tied directly to IN. The NCP707 is a high performance, small package size, 200 mA LDO voltage regulator. This device delivers very good noise and dynamic performance. Thanks to its adaptive ground current feature the device consumes only 25 mA of quiescent current at no−load condition. The regulator features very*low noise of 22 mVRMS, PSRR of typ. 70dB at 1kHz and very good load/line transient response. The device is an ideal choice for space constrained portable applications. A logic EN input provides ON/OFF control of the output voltage. When the EN is low the device consumes as low as typ. 10 nA from the IN pin. The device is fully protected in case of output overload, output short circuit condition and overheating, assuring a very robust design. Reverse Current The PMOS pass transistor has an inherent body diode which will be forward biased in the case that VOUT > VIN. Due to this fact in cases where the extended reverse current condition is anticipated the device may require additional external protection. Input Capacitor Selection (CIN) It is recommended to connect a minimum of 1 μF Ceramic X5R or X7R capacitor close to the IN pin of the device. Larger input capacitors may be necessary if fast and large load transients are encountered in the application. There is no requirement for the min./max. ESR of the input capacitor but it is recommended to use ceramic capacitors for their low ESR and ESL. Output Current Limit Output Current is internally limited within the IC to a typical 379 mA. The NCP707 will source this amount of current measured with the output voltage 100 mV lower than the nominal VOUT. If the Output Voltage is directly shorted to ground (VOUT = 0 V), the short circuit protection will limit the output current to 390 mA (typ). The current limit and short circuit protection will work properly up to VIN =5.5 V at TA = 25°C. There is no limitation for the short circuit duration. Output Capacitor Selection (COUT) The NCP707 is designed to be stable with small 1.0 mF and larger ceramic capacitors on the output. The minimum effective output capacitance for which the LDO remains stable is 100 nF. The safety margin is provided to account for capacitance variations due to DC bias voltage, temperature, initial tolerance. There is no requirement for the minimum value of Equivalent Series Resistance (ESR) for the COUT but the maximum value of ESR should be less than 700 mΩ. Larger output capacitors could be used to improve the load transient response or high frequency PSRR characteristics. It is not recommended to use tantalum capacitors on the output due to their large ESR. The equivalent series resistance of tantalum capacitors is also strongly dependent on the temperature, increasing at low temperature. The tantalum capacitors are generally more costly than ceramic capacitors. Thermal Shutdown When the die temperature exceeds the Thermal Shutdown threshold (TSD * 160°C typical), Thermal Shutdown event is detected and the device is disabled. The IC will remain in this state until the die temperature decreases below the Thermal Shutdown Reset threshold (TSDU − 140°C typical). Once the IC temperature falls below the 140°C the LDO is enabled again. The thermal shutdown feature provides protection from a catastrophic device failure due to accidental overheating. This protection is not intended to be used as a substitute for proper heat sinking. No−load Operation Power Dissipation The regulator remains stable and regulates the output voltage properly within the ±2% tolerance limits even with no external load applied to the output. As power dissipated in the NCP707 increases, 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 the ambient temperature affect the rate of junction temperature rise for the part. The maximum power dissipation the NCP707 can handle is given by: Enable Operation The NCP707 uses the EN pin to enable/disable its output and to control the active discharge function. If the EN pin voltage is < 0.4 V the device is guaranteed to be disabled. The pass transistor is turned*off so that there is virtually no current flow between the IN and OUT. In case of the option equipped with active discharge − the active discharge transistor is turned−on and the output voltage VOUT is pulled P D(MAX) + www.onsemi.com 16 ƪ125 * T Aƫ q JA (eq. 1) NCP707 For reliable operation junction temperature should be limited to +125°C. The power dissipated by the NCP707 for given application conditions can be calculated as follows: P D(MAX) + V INI GND ) I OUTǒV IN * V OUTǓ point of load can easily approach 100 mW which will cause a 20 mV voltage drop at full load current, deteriorating the excellent load regulation. Line Regulation (eq. 2) The IC features very good line regulation of 0.4 mV/V measured from VIN = VOUT + 0.5 V to 5.5 V. Figure 68 shows the typical values of θJA vs. heat spreading area. Power Supply Rejection Ratio At low frequencies the PSRR is mainly determined by the feedback open−loop gain. At higher frequencies in the range 100 kHz – 10 MHz it can be tuned by the selection of COUT capacitor and proper PCB layout. Load Regulation The NCP707 features very good load regulation of typical 2 mV in the 0 mA to 200 mA range. In order to achieve this very good load regulation a special attention to PCB design is necessary.

Thermal Parameters vs. Copper Area Output Noise voltage overshoots and assures monotonic ramp−up of the output voltage. The IC is designed for very−low output voltage noise. The typical noise performance of 22 mVRMS makes the device suitable for noise sensitive applications. PCB Layout Recommendations To obtain good transient performance and good regulation characteristics place CIN and COUT capacitors close to the device pins and make the PCB traces wide. In order to minimize the solution size use 0402 capacitors. Larger copper area connected to the pins will also improve the device thermal resistance. The actual power dissipation can be calculated by the formula given in Equation 2. Internal Soft Start The Internal Soft*Start circuitry will limit the inrush current during the LDO turn−on phase.
