Enable Turn-off - Various Output Capacitors www.onsemi.com 12 NCP163 APPLICATIONS INFORMATION General 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. The NCP163 is an ultra-low noise 250 mA low dropout regulator designed to meet the requirements of RF applications and high performance analog circuits. The NCP163 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 NCP163 is fully protected in case of current overload, output short circuit and overheating. Enable Operation 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 mF 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. The NCP163 uses the EN pin to enable/disable its device and to deactivate/activate 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. The active discharge transistor is active so that the output voltage VOUT is pulled to GND through a 280 W resistor. In the disable state the device consumes as low as typ. 10 nA from the VIN. If the EN pin voltage >1.2 V the device is guaranteed to be enabled. The NCP163 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 200 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 Decoupling (COUT) Output Current Limit Input Capacitor Selection (CIN) The NCP163 requires an output capacitor connected as close as possible to the output pin of the regulator. The recommended capacitor value is 1 mF and X7R or X5R dielectric due to its low capacitance variations over the specified temperature range. The NCP163 is designed to remain stable with minimum effective capacitance of 0.7 mF to account for changes with temperature, DC bias and package size. Especially for small package size capacitors such as 0201 the effective capacitance drops rapidly with the applied DC bias. Please refer Figure 47. Output Current is internally limited within the IC to a typical 700 mA. The NCP163 will source this amount of current measured with a voltage drops on the 90% of 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 690 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 (TSD - 160C 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 - 140C typical). Once the IC temperature falls below the 140C 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 NCP163 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 Figure 47. Capacity vs DC Bias Voltage 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 2 W. Larger output capacitors and lower ESR could improve the load www.onsemi.com 13 NCP163 ambient temperature affect the rate of junction temperature rise for the part.

Due to this fact in cases, where the extended reverse current condition can be anticipated the device may require additional external protection. The turn-on time is defined as the time period from EN assertion to the point in which VOUT will reach 98% of its nominal value. This time is dependent on various application conditions such as VOUT(NOM), COUT, TA. Power Supply Rejection Ratio 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 or 0201 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. PCB Layout Recommendations The NCP163 features very high Power Supply Rejection ratio. If desired the PSRR at higher frequencies in the range 100 kHz - 10 MHz can be tuned by the selection of COUT capacitor and proper PCB layout. www.onsemi.com 16 NCP163 ORDERING INFORMATION (WLCSP4) Voltage Option Marking Rotation NCP163AFCS120T2G 1.2 V 2 0 NCP163AFCS180T2G 1.8 V Y 180 NCP163AFCS250T2G 2.5 V T 270 NCP163AFCS260T2G 2.6 V 4 180 NCP163AFCS270T2G 2.7 V V 270 NCP163AFCS280T2G 2.8 V 3 180 NCP163AFCS285T2G 2.85 V 5 180 NCP163AFCS290T2G 2.9 V 6 180 NCP163AFCS2925T2G 2.925 V 2 180 NCP163AFCS514T2G 5.14 V 3 270 NCP163BFCS180T2G 1.8 V Y 270 NCP163BFCS2925T2G 2.925 V 2 270 NCP163AFCT120T2G 1.2 V A 0 NCP163AFCT180T2G 1.8 V Y 180 NCP163AFCT250T2G 2.5 V Y 90 NCP163AFCT260T2G 2.6 V 6 270 NCP163AFCT270T2G 2.7 V 5 180 NCP163AFCT280T2G 2.8 V 3 180 NCP163AFCT285T2G 2.85 V 5 270 NCP163AFCT290T2G 2.9 V 4 270 NCP163AFCT2925T2G 2.925 V 2 180 NCP163AFCT300T2G 3.0 V 3 270 NCP163AFCT330T2G 3.3 V 6 90 NCP163AFCT514T2G 5.14 V T 0 NCP163BFCT180T2G 1.8 V Y 270 NCP163BFCT2925T2G 2.925 V 2 270 Device Description 250 mA, Active Discharge Package Shipping WLCSP4 CASE 567KA (Pb-Free) 5000 / Tape & Reel WLCSP4 CASE 567JZ (Pb-Free) 5000 / Tape & Reel 250 mA, Non-Active Discharge 250 mA, Active Discharge 250 mA, Non-Active Discharge 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. www.onsemi.com 17 NCP163 ORDERING INFORMATION (XDFN4) Voltage Option Marking NCP163AMX120TBG* 1.2 V ME NCP163AMX130TBG* 1.3 V MG NCP163AMX150TBG 1.5 V MV NCP163AMX180TBG 1.8 V MA NCP163AMX1825TBG 1.825 V MC NCP163AMX190TBG 1.9 V MH NCP163AMX250TBG 2.5 V MU NCP163AMX260TBG 2.6 V MN NCP163AMX270TBG 2.7 V MX NCP163AMX275TBG 2.75 V MD NCP163AMX280TBG 2.8 V MM NCP163AMX285TBG 2.85 V MQ NCP163AMX290TBG 2.9 V MR NCP163AMX300TBG 3.0 V MJ NCP163AMX330TBG 3.3 V MK NCP163AMX400TBG 4.0 V MY NCP163AMX500TBG 5.0 V ML NCP163AMX514TBG 5.14 V MW NCP163BMX180TBG 1.8 V PA NCP163BMX1825TBG 1.825 V PC NCP163BMX275TBG 2.75 V PD Device Description Package Shipping XDFN4 CASE 711AJ (Pb-Free) 3000 / Tape & Reel 250 mA, Active Discharge 250 mA, Non-Active Discharge 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. *Contact sales office for availability information.
