5 NCP, NCV 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 % below its nominal. The junction temperature, load current, and minimum input supply requirements affect the dropout level. 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 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 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 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. C. Depending on the ambient power dissipation and thus the maximum available output current.

9 NCP, NCV APPLICATIONS INFORMATION A typical application circuit for the NCP series is shown in Figure. Input Decoupling (C) A. F capacitor either ceramic or tantalum is recommended and should be connected close to the NCP package. Higher values and lower ESR will improve the overall line transient response. Output Decoupling (C) The NCP is a stable Regulator and does not require any specific Equivalent Series Resistance (ESR) or a minimum output current. Capacitors exhibiting ESRs ranging from a few m up to. can thus safely be used. The minimum decoupling value is. 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. Enable Operation The enable pin will turn on or off the regulator. These limits of threshold are covered in the electrical specification section of this data sheet. If the enable is not used then the pin should be connected to V in. Hints Please be sure the V in 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. Set 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 NCP 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 also the ambient temperature effect the rate of temperature rise for the part. This is stating that when the NCP has 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: PD T J(max) TA R JA If junction temperature is not allowed above the maximum C, then the NCP can dissipate up to C. The power dissipated by the NCP can be calculated from the following equation: or Ptot V in *Ignd (Iout) [V in Vout ] *I out VinMAX P tot Vout * Iout IGND Iout If a ma output current is needed then the ground current from the data sheet is.

Resistor R in conjunction with V BE of the PNP determines when the pass transistor begins conducting; this circuit is not short circuit proof. Input/Output differential voltage minimum is increased by V BE of the pass resistor. Figure.

Resistor R, and capacitor C, will delay the turnon of the bottom regulator. Figure. Input Voltages Greater than V A regulated output can be achieved with input voltages that exceed the V maximum rating of the NCP series with the addition of a simple preregulator circuit. Care must be taken to prevent Q from overheating when the regulated output (V out ) is shorted to GND.
