12 APPLICATIONS INFORMATION General The NCP161 is an ultra low noise 45 ma low dropout regulator designed to meet the requirements of RF applications and high performance analog circuits. The NCP161 device provides very high PSRR and excellent dynamic response. In connection with low quiescent current this device is well suitable for battery powered application such as cell phones, tablets and other. The NCP161 is fully protected in case of current overload, output short circuit and overheating. Input Capacitor Selection (C IN ) Input capacitor connected as close as possible is necessary for ensure device stability. The X7R or X5R capacitor should be used for reliable performance over temperature range. The value of the input capacitor should be 1 F or greater to ensure the best dynamic performance. This capacitor will provide a low impedance path for unwanted AC signals or noise modulated onto constant input voltage. There is no requirement for the ESR of the input capacitor but it is recommended to use ceramic capacitors for their low ESR and ESL. A good input capacitor will limit the influence of input trace inductance and source resistance during sudden load current changes. Output Decoupling (C OUT ) The NCP161 requires an output capacitor connected as close as possible to the output pin of the regulator. The recommended capacitor value is 1 F and X7R or X5R dielectric due to its low capacitance variations over the specified temperature range. The NCP161 is designed to remain stable with minimum effective capacitance of.7 F to account for changes with temperature, DC bias and package size. Especially for small package size capacitors such as 21 the effective capacitance drops rapidly with the applied DC bias. Please refer Figure 49. Figure 49. Capacity vs DC Bias Voltage There is no requirement for the minimum value of Equivalent Series Resistance (ESR) for the C OUT but the maximum value of ESR should be less than 2 Ω. Larger output capacitors and lower ESR could improve the load transient response or high frequency PSRR. 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. Enable Operation The NCP161 uses the EN pin to enable/disable its device and to deactivate/activate the active discharge function. If the EN pin voltage is <.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. The active discharge transistor is active so that the output voltage is pulled to GND through a 28 Ω resistor. In the disable state the device consumes as low as typ. 1 na from the V IN. If the EN pin voltage >1.2 V the device is guaranteed to be enabled. The NCP161 regulates the output voltage and the active discharge transistor is turned off. The EN pin has internal pull down current source with typ. value of 2 na which assures that the device is turned off when the EN pin is not connected. In the case where the EN function isn t required the EN should be tied directly to IN. Output Current Limit Output Current is internally limited within the IC to a typical 7 ma. The NCP161 will source this amount of current measured with a voltage drops on the 9% of the nominal. If the Output Voltage is directly shorted to ground ( = V), the short circuit protection will limit the output current to 69 ma (typ). The current limit and short circuit protection will work properly over whole temperature range and also input voltage range. There is no limitation for the short circuit duration. Thermal Shutdown When the die temperature exceeds the Thermal Shutdown threshold (T SD 16 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 (T SDU 14 C typical). Once the IC temperature falls below the 14 C the LDO is enabled again. The thermal shutdown feature provides the 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. Power Dissipation As power dissipated in the NCP161 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 12

13 ambient temperature affect the rate of junction temperature rise for the part. The maximum power dissipation the NCP161 can handle is given by: 125o C T A P D(MAX) (eq. 1) JA The power dissipated by the NCP161 for given application conditions can be calculated from the following equations: P D V IN I GND I OUT VIN (eq. 2) JA, JUNCTION TO AMBIENT THERMAL RESISTANCE ( C/W) 16 P D(MAX), T A = 25 C, 2 oz Cu P D(MAX), T A = 25 C, 1 oz Cu JA, 1 oz Cu 1 JA, 2 oz Cu PCB COPPER AREA (mm 2 ) Figure 5.

JA and P D (MAX) vs. Copper Area (XDFN4) P D(MAX), MAXIMUM POWER DISSIPATION (W) 13

14 Reverse Current The PMOS pass transistor has an inherent body diode which will be forward biased in the case that > V IN. Due to this fact in cases, where the extended reverse current condition can be anticipated the device may require additional external protection. Power Supply Rejection Ratio The NCP161 features very high Power Supply Rejection ratio. If desired the PSRR at higher frequencies in the range 1 khz 1 MHz can be tuned by the selection of C OUT capacitor and proper PCB layout. Turn On Time The turn on time is defined as the time period from EN assertion to the point in which will reach 98% of its nominal value. This time is dependent on various application conditions such as (NOM), C OUT, T A. PCB Layout Recommendations To obtain good transient performance and good regulation characteristics place C IN and C OUT capacitors close to the device pins and make the PCB traces wide. In order to minimize the solution size, use 42 or 21 capacitors with appropriate capacity. Larger copper area connected to the pins will also improve the device thermal resistance. The actual power dissipation can be calculated from the equation above (Equation 2). Expose pad can be tied to the GND pin for improvement power dissipation and lower device temperature. 14
