Output Voltage Noise http://onsemi.com 5 450 500 1000 NCP662, NCV662, NCP663, NCV663 DEFINITIONS Load Regulation Line Regulation The change in output voltage for a change in output current at a constant temperature. The change in output voltage for a change in input voltage. The measurement is made under conditions of low dissipation or by using pulse technique such that the average chip temperature is not significantly affected. Dropout Voltage The input/output differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 3.0% below its nominal. The junction temperature, load current, and minimum input supply requirements affect the dropout level. Line Transient Response Typical over and undershoot response when input voltage is excited with a given slope. Thermal Protection Internal thermal shutdown circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. When activated at typically 160°C, the regulator turns off. This feature is provided to prevent failures from accidental overheating. Maximum Power Dissipation The maximum total dissipation for which the regulator will operate within its specifications. Quiescent Current The quiescent current is the current which flows through the ground when the LDO operates without a load on its output: internal IC operation, bias, etc. When the LDO becomes loaded, this term is called the Ground current. It is actually the difference between the input current (measured through the LDO input pin) and the output current. Maximum Package Power Dissipation The maximum power package dissipation is the power dissipation level at which the junction temperature reaches its maximum operating value, i.e. 125°C. Depending on the ambient power dissipation and thus the maximum available output current. http://onsemi.com 6 NCP662, NCV662, NCP663, NCV663 APPLICATIONS INFORMATION A typical application circuit for the NCP662/NCV662 and NCP663/NCV663 series are shown in Figure 1 and Figure 2. Place external components, especially the output capacitor, as close as possible to the circuit, and make leads as short as possible. Input Decoupling (C1) Thermal A 1.0 F capacitor, either ceramic or tantalum is recommended and should be connected close to the device package. Higher capacitance values and lower ESR will improve the overall line transient response. TDK capacitor: C2012X5R1C105K or C1608X5R1A105K As power across the NCP662/NCV662 and NCP663/NCV663 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. The mounting pad configuration on the PCB, the board material, and the ambient temperature effect the rate of temperature rise for the part. This is stating that when the devices have good thermal conductivity through the PCB, the junction temperature will be relatively low with high power dissipation applications. The maximum dissipation the package can handle is given by: Output Decoupling (C2) The NCP662/NCV662 and NCP663/NCV663 are very stable regulators and do not require any specific Equivalent Series Resistance (ESR) or a minimum output current. Capacitors exhibiting ESRs ranging from a few m up to 10 can safely be used. The minimum decoupling value is 0.1 F and can be augmented to fulfill stringent load transient requirements. The regulator accepts ceramic chip capacitors as well as tantalum devices. Larger values improve noise rejection and load regulation transient response. TDK capacitor: C2012X5R1C105K, C1608X5R1A105K, or C3216X7R1C105K T TA PD J(max) RJA If junction temperature is not allowed above the maximum 125°C, then the NCP662/NCV662 and NCP663/NCV663 can dissipate up to 300 mW @ 25°C. The power dissipated by the NCP662/NCV662 and NCP663/NCV663 can be calculated from the following equation: Enable Operation (NCP662/NCV662 ONLY) The enable pin will turn on the regulator when pulled high and turn off the regulator when pulled low. The threshold limits are covered in the electrical specification section of the data sheet. If the enable is not used, the pin should be connected to Vin. Ptot [Vin * Ignd (Iout)] [Vin Vout] * Iout or P Vout * Iout VinMAX tot Ignd Iout If an 100 mA output current is needed then the ground current from the data sheet is 2.5 A. For the NCP662/NCV662 or NCP663/NCV663 (3.0 V), the maximum input voltage is 6.0 V. Hints Please be sure the Vin and GND lines are sufficiently wide. When the impedance of these lines is high, there is a chance to pick up noise or cause the regulator to malfunction. http://onsemi.com 7 NCP662, NCV662, NCP663, NCV663 ORDERING INFORMATION Nominal Output Voltage Marking NCP662SQ15T1 1.5 LGY NCP662SQ15T1G 1.5 LGY NCP662SQ18T1 1.8 LGZ NCP662SQ18T1G 1.8 LGZ NCP662SQ25T1 2.5 LHA NCP662SQ25T1G 2.5 LHA NCP662SQ27T1 2.7 LHB NCP662SQ27T1G 2.7 LHB NCP662SQ28T1 2.8 LHC NCP662SQ28T1G 2.8 LHC NCP662SQ30T1 3.0 LHD NCP662SQ30T1G 3.0 LHD NCP662SQ33T1 3.3 LHE NCP662SQ33T1G 3.3 LHE NCP662SQ50T1 5.0 LHF NCP662SQ50T1G 5.0 LHF NCP663SQ15T1 1.5 LHG NCP663SQ15T1G 1.5 LHG NCP663SQ18T1 1.8 LHH NCP663SQ18T1G 1.8 LHH NCP663SQ25T1 2.5 LHI NCP663SQ25T1G 2.5 LHI NCP663SQ27T1 2.7 LHJ NCP663SQ27T1G 2.7 LHJ NCP663SQ28T1 2.8 LHK NCP663SQ28T1G 2.8 LHK NCP663SQ30T1 3.0 LHL NCP663SQ30T1G 3.0 LHL NCP663SQ33T1 3.3 LHM NCP663SQ33T1G 3.3 LHM NCP663SQ50T1 5.0 LHN NCP663SQ50T1G 5.0 LHN Device Package Shipping† SC82 AB SC82−AB 3000 Units/ 8″ Tape & Reel SC82−AB 3000 Units/ 8″ Tape & Reel †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. http://onsemi.com 8 NCP662, NCV662, NCP663, NCV663 ORDERING INFORMATION Nominal Output Voltage Marking NCV662SQ15T1 1.5 LGY NCV662SQ15T1G 1.5 LGY NCV662SQ18T1 1.8 LGZ NCV662SQ18T1G 1.8 LGZ NCV662SQ25T1 2.5 LHA NCV662SQ25T1G 2.5 LHA NCV662SQ27T1 2.7 LHB NCV662SQ27T1G 2.7 LHB NCV662SQ28T1 2.8 LHC NCV662SQ28T1G 2.8 LHC NCV662SQ30T1 3.0 LHD NCV662SQ30T1G 3.0 LHD NCV662SQ33T1 3.3 LHE NCV662SQ33T1G 3.3 LHE NCV662SQ50T1 5.0 LHF NCV662SQ50T1G 5.0 LHF NCV663SQ15T1 1.5 LHG NCV663SQ15T1G 1.5 LHG NCV663SQ18T1 1.8 LHH NCV663SQ18T1G 1.8 LHH NCV663SQ25T1 2.5 LHI NCV663SQ25T1G 2.5 LHI NCV663SQ27T1 2.7 LHJ NCV663SQ27T1G 2.7 LHJ NCV663SQ28T1 2.8 LHK NCV663SQ28T1G 2.8 LHK NCV663SQ30T1 3.0 LHL NCV663SQ30T1G 3.0 LHL NCV663SQ33T1 3.3 LHM NCV663SQ33T1G 3.3 LHM NCV663SQ50T1 5.0 LHN NCV663SQ50T1G 5.0 LHN Device Package Shipping† SC82 AB SC82−AB 3000 Units/ 8″ Tape & Reel SC82−AB 3000 Units/ 8″ Tape & Reel †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. http://onsemi.com 9 NCP662, NCV662, NCP663, NCV663 PACKAGE DIMENSIONS SC82−AB (SC70−4) SQ SUFFIX CASE 419C−02 ISSUE C A G C D 3 PL N 4 3 1 2 K B S F L H J 0.05 (0.002) NOTES: 1.
