NCP662, NCV662, NCP663, NCV663
100 mA CMOS Low Iq Low−Dropout Voltage Regulator
This series of fixed output low−dropout linear regulators are designed for handheld communication equipment and portable battery powered applications which require low quiescent current. This series features an ultra−low quiescent current of 2.5 A. Each device contains a voltage reference unit, an error amplifier, a PMOS power transistor, resistors for setting output voltage, current limit, and temperature limit protection circuits. The NCP662/NCV662 series provides an enable pin for ON/OFF control.
This series has been designed to be used with low cost ceramic capacitors and requires a minimum output capacitor of 0.1 F. The device is housed in the micro−miniature SC82−AB surface mount package. Standard voltage versions are 1.5, 1.8, 2.5, 2.7, 2.8, 3.0, 3.3, and 5.0 V.

DEFINITIONS
Load Regulation
The change in output voltage for a change in output
current at a constant temperature.
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 r equirements a ffect t he d ropout l e vel.
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.
Line Regulation
The change in output voltage for a change in input voltage. The measurement is made under conditions of low dissipation or b y 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
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.

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)
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
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
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 V
Hints
.
in
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.
Place external components, especially the output capacitor, as close as possible to the circuit, and make leads as short as possible.
Thermal
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 e f fect 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:

R
JA
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:

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.
