Output Voltage Noise Spectral Density for VOUT = 1.8 V, IOUT = 10 mA, COUT = 10 mF APPLICATIONS INFORMATION operating current is between 10 mA and 1 mA to obtain low saturation voltage. External pull−up resistor can be connected to any voltage up to 5.5 V (please see Absolute Maximum Ratings table above). The NCP187 is the member of new family of high output current and low dropout regulators which delivers low quiescent and ground current consumption, good noise and power supply ripple rejection ratio performance. The NCP187 incorporates EN pin and power good output for simple controlling by MCU or logic. Standard features include current limiting, soft−start feature and thermal protection. Power Dissipation and Heat Sinking 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. For reliable operation junction temperature should be limited to +125_C. The maximum power dissipation the NCP187 can handle is given by: Input Decoupling (CIN) It is recommended to connect at least 1 mF ceramic X5R or X7R capacitor between IN and GND pin of the device. This capacitor will provide a low impedance path for any unwanted AC signals or noise superimposed onto constant input voltage. The good input capacitor will limit the influence of input trace inductances and source resistance during sudden load current changes. Higher capacitance and lower ESR capacitors will improve the overall line transient response. P D(MAX) + ƪTJ(MAX) * TAƫ (eq. 1) R qJA The power dissipated by the NCP187 for given application conditions can be calculated from the following equations: P D [ V INǒI GND(I OUT)Ǔ ) I OUTǒV IN * V OUTǓ Output Decoupling (COUT) The NCP187 does not require a minimum Equivalent Series Resistance (ESR) for the output capacitor. The device is designed to be stable with standard ceramics capacitors with values of 4.7 mF or greater. Recommended capacitor for the best performance is 10 mF. The X5R and X7R types have the lowest capacitance variations over temperature thus they are recommended. (eq. 2) or V IN(MAX) [ P D(MAX) ) ǒV OUT I OUT ) I GND I OUTǓ (eq. 3) Hints VIN and GND printed circuit board traces should be as wide as possible. When the impedance of these traces is high, there is a chance to pick up noise or cause the regulator to malfunction. Place external components, especially the output capacitor, as close as possible to the NCP187, and make traces as short as possible. Power Good Output Connection The NCP187 include Power Good functionality for better interfacing to MCU system. Power Good output is open collector type, capable to sink up to 10 mA.

Do not operate the device at output voltage about 5.2 V, as device can be damaged. In order to avoid influence of current flowing into SNS pin to output voltage accuracy (SNS current varies with voltage option and temperature, typical value is 300 nA) it is recommended to use values of R1 and R2 below 500 kW. Not only adjustable version, but also any fixed version can be used to create adjustable voltage, where original fixed voltage becomes reference voltage for resistor divider and feedback loop. Output voltage can be equal or higher than original fixed option, while possible range is from 0.8 V up to 5.2 V. Picture below shows how to add external resistors to increase output voltage above fixed value. Output voltage is then given by equation: V OUT + V FIX (1 ) R1ńR2) VIN VOUT IN NCP187 ADJ or FIX version 1 mF Ceramic CIN OUT EN GND R1 SNS ON R2 OFF COUT 10 mF Ceramic Figure 16. recommended to use as high fixed variant as possible – for example in case above it is better to use 3.3 V fixed variant to create 3.6 V output voltage, as output noise will be amplified only 3.6/3.3 = 1.09 × (16.4 mVrms). Please note that output noise is amplified by VOUT / VFIX ratio. For example, if original 0.8 V fixed variant is used to create 3.6 V output voltage, output noise is increased 3.6/0.8 = 4.5 times and real value will be 4.5 × 15 mVrms = 67.5ĂmVrms .
