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. Maximum Power Dissipation 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. Line Transient Response Typical over and undershoot response when input voltage is excited with a given slope. Thermal Protection 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. 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 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. Input Decoupling (C1) Place external components, especially the output capacitor, as close as possible to the circuit, and make leads as short as possible. Thermal A 1.0 mF 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 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 mW up to 10 W can safely be used. The minimum decoupling value is 0.1 mF 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 Enable Operation (NCP662/NCV662 ONLY) 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: T *TA PD + J(max) RqJA 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: Ptot + [Vin * Ignd (Iout)] ) [Vin * Vout] * Iout 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. Hints or P ) Vout * Iout VinMAX + tot Ignd ) Iout 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. If an 100 mA output current is needed then the ground current from the data sheet is 2.5 mA. For the NCP662/NCV662 or NCP663/NCV663 (3.0 V), the maximum input voltage is 6.0 V. http://onsemi.com 7 NCP662, NCV662, NCP663, NCV663 ORDERING INFORMATION Device NCP662SQ15T1 NCP662SQ15T1G NCP662SQ18T1 NCP662SQ18T1G NCP662SQ25T1 NCP662SQ25T1G NCP662SQ27T1 NCP662SQ27T1G NCP662SQ28T1 NCP662SQ28T1G NCP662SQ30T1 NCP662SQ30T1G NCP662SQ33T1 NCP662SQ33T1G NCP662SQ50T1 NCP662SQ50T1G NCP663SQ15T1 NCP663SQ15T1G NCP663SQ18T1 NCP663SQ18T1G NCP663SQ25T1 NCP663SQ25T1G NCP663SQ27T1 NCP663SQ27T1G NCP663SQ28T1 NCP663SQ28T1G NCP663SQ30T1 NCP663SQ30T1G NCP663SQ33T1 NCP663SQ33T1G NCP663SQ50T1 NCP663SQ50T1G Nominal Output Voltage 1.5 1.5 1.8 1.8 2.5 2.5 2.7 2.7 2.8 2.8 3.0 3.0 3.3 3.3 5.0 5.0 1.5 1.5 1.8 1.8 2.5 2.5 2.7 2.7 2.8 2.8 3.0 3.0 3.3 3.3 5.0 5.0 Marking LGY LGY LGZ LGZ LHA LHA LHB LHB LHC LHC LHD LHD LHE LHE LHF LHF LHG LHG LHH LHH LHI LHI LHJ LHJ LHK LHK LHL LHL LHM LHM LHN LHN SC82−AB 3000 Units/ Units/ 8″ Tape & Reel SC82−AB SC82 AB 3000 Units/ Units/ 8″ Tape & Reel Package Shipping† †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 Device NCV662SQ15T1 NCV662SQ15T1G NCV662SQ18T1 NCV662SQ18T1G NCV662SQ25T1 NCV662SQ25T1G NCV662SQ27T1 NCV662SQ27T1G NCV662SQ28T1 NCV662SQ28T1G NCV662SQ30T1 NCV662SQ30T1G NCV662SQ33T1 NCV662SQ33T1G NCV662SQ50T1 NCV662SQ50T1G NCV663SQ15T1 NCV663SQ15T1G NCV663SQ18T1 NCV663SQ18T1G NCV663SQ25T1 NCV663SQ25T1G NCV663SQ27T1 NCV663SQ27T1G NCV663SQ28T1 NCV663SQ28T1G NCV663SQ30T1 NCV663SQ30T1G NCV663SQ33T1 NCV663SQ33T1G NCV663SQ50T1 NCV663SQ50T1G Nominal Output Voltage 1.5 1.5 1.8 1.8 2.5 2.5 2.7 2.7 2.8 2.8 3.0 3.0 3.3 3.3 5.0 5.0 1.5 1.5 1.8 1.8 2.5 2.5 2.7 2.7 2.8 2.8 3.0 3.0 3.3 3.3 5.0 5.0 Marking LGY LGY LGZ LGZ LHA LHA LHB LHB LHC LHC LHD LHD LHE LHE LHF LHF LHG LHG LHH LHH LHI LHI LHJ LHJ LHK LHK LHL LHL LHM LHM LHN LHN SC82−AB 3000 Units/ Units/ 8″ Tape & Reel SC82−AB SC82 AB 3000 Units/ Units/ 8″ Tape & Reel Package Shipping† †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 D 3 PL 4 3 C N NOTES: 1.
