Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible. MOTOROLA ANALOG IC DEVICE DATA MC78LC00 Series DEFINITIONS Dropout Voltage – The input/output voltage differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 100 mV below its nominal value (which is measured at 1.0 V differential), dropout voltage is affected by junction temperature, load current and minimum input supply requirements. 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 techniques such that average chip temperature is not significantly affected. Load Regulation – The change in output voltage for a change in load current at constant chip temperature. Maximum Power Dissipation – The maximum total device dissipation for which the regulator will operate within specifications. Quiescent Bias Current – Current which is used to operate the regulator chip and is not delivered to the load. Figure 1. Output Voltage versus Input Voltage Figure 2.

An input bypass capacitor is recommended if the regulator is located an appreciable distance (≥ 4 inches) from the input voltage source. These regulators require ≥ 0.1 µF capacitance between the output terminal and ground for stability. Most types of aluminum, tantalum or multilayer ceramic will perform adequately. Solid tantalums or other appropriate capacitors are recommended for operation below 25°C. The bypass capacitors should be mounted with the shortest possible leads or track lengths directly across the regulator input and output terminals. With economical electrolytic capacitors, cold temperature operation can pose a serious stability problem. As the electrolyte freezes, around –30°C, the capacitance will decrease and the equivalent series resistance (ESR) will increase drastically, causing the circuit to oscillate. Quality electrolytic capacitors with extended temperature ranges of –40° to +85°C are readily available. Solid tantalum capacitors may be the better choice if small size is a requirement. However, a maximum ESR limit of 3.0 Ω must be observed over temperature to maintain stability. In the Current Boost Circuit, shown in Figures 10 and 12, an output current of up to 600 mA can be delivered by the circuit. The circuit of Figure 10 has no current limit. In each case, the external transistor must be rated for the expected power dissipation. Figure 11 shows how a fixed output may be programmed, using R1 and R2, to provide a higher output voltage.
