DEFINITIONS Load Regulation difference between the input current (measured through the LDO input pin) and the output current. The change in output voltage for a change in output current at a constant temperature. Line Regulation Dropout Voltage 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. 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% 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. Maximum Power Dissipation The maximum total dissipation for which the regulator will operate within its specifications. 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. 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.

As power across the MC78LC00 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 MC78LC00 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: Input Decoupling (C1) A 0.1 mF capacitor either ceramic or tantalum is recommended and should be connected close to the MC78LC00 package. Higher values and lower ESR will improve the overall line transient response. Output Decoupling (C2) The MC78LC00 is a stable component and does not require any specific Equivalent Series Resistance (ESR) or a minimum output current. Capacitors exhibiting ESRs ranging from a few mW up to 3.0 W can thus 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. PD + If junction temperature is not allowed above the maximum 125°C, then the MC78LC00NTR can dissipate up to 357 mW @ 25°C. The power dissipated by the MC78LC00NTR can be calculated from the following equation: 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. Set external components, especially the output capacitor, as close as possible to the circuit, and make leads as short as possible.
