Design a regulator using 1C 723 to meet thejollowing specifications : "V0 = 5V; I0 = 100 mA. Vm = 15 ± 20 % Ist = 150 mA; Vsense = 0.7 V. [Marks10] 2. Write an problems with EPROMs that have a 10 percent powersupply tolerance; in other words, ones that are guaranteed to operate from supplies of 4.5 to 5.5V. You do want to be sure that your main supply is a solid +5V, or even a little higher. The data sheets In this case, you will be operating near orjust below the recommended supply voltage, especially if your main supply is slightly under +5V. When you are not Each regulating circuit uses an LM317 adjustable regulator. You set the from National Semiconductors.are available in the voltage ratings of 5V, 12V and 15V whereas Motorola devices are available in the voltage ratings of 5V, 6V, 8V, 12V, 15V, 18V, 20V and 24V. Different package types along with their lead identification are depicted in Fig. 1.54. LM140XX/LM340XX series LM140XX/LM340XX series regulators are again fixed output voltage regulators available in a variety of output voltage and output current specifications. LM117/LM217/LM317 Figure 7.3 * A Practical StepDown Regulator Using the LT1074 Figure 7.4 * Waveforms for the StepDown Regulator at VIN = 28V and VOUT = 5V at 1A operating waveforms for the regulator at VIN = 28V with a 5V, 1A load. Trace A is the VSW pin voltage Figure 7.6 compares this circuit's efficiency.with linear regulators in a common and important situation. Efficient regulation under given on the horizontal axis. Efficiency for the LM317 and LT1086 linear regulators suffers over the Figure 32: The “hairwired” version of the voltage regulator circuit with a heat sink screwed to the LM317 (left) and a breadboard version of the regulator (right). I used this in an application with minimal power requirements and thus did not include the heat sink. While those regulator circuits worked, one reason for using the more refined Regulated Power Supply format in Figure 31 was to eliminate the awkward trimmer potentiometer and instead use a standard 270degree Power is dissipated by the regulator in an amount equivalent to.the difference between the regulator's input and output voltages multiplied by the current through it. In this instance, (16V 5V) X 1.5 A = 16.5 W The conversion efficiency is VCHT/V/.V = 5/16 = 31% The LM317 and similar linear regulators (shown in figure 1) such as the 7805 and LM340 are all called series dissipative regulators. They function in a linear mode, simulating a variable resistance between the input voltage The circuit as shown in Fig. I makes use of astable multivibrator for power flasher using 1C 555. The unregulated supply is derived from transformer XI and two diodes D I and D2 connected in fullwave rectifier fashion. This supply is given to LM317, an adjustable voltage regulator capable of providing 1 .2V to 37V.DC output. LM317 functions normally. If sufficient load is 1 Regulated 5V is given to astable multivibrator circuit comprising 1C 555. Output of 1C 555 is given to the base of This book does that task for thempulls out those features that they need to know about and shows them how to make use of them in specific design examples that they can then tailor to their own design needs. *This is the ONLY book to deal The peak rectified voltage that appears at the filter capacitor is 1.4 times the AC input voltage (AC input voltage is a root mean square [RMS] figure). A 10V AC will you would choose the 7805 regulator for 5V output voltage. It can provide up to 1A output current and can be fed a DC input voltage between 9V and 20V. You could.also choose an LM317 threeterminal variable voltage regulator and adjust the output voltage to 1.25V and above with the help of two resistors. A voltage
