3) Improved reliability for the power supply using these regulators. Thus, adjustable voltage regulators have become more popular because of their versatility, performance, and reliability. The LM317 is the most widely used adjustable voltage regulator series. 10.13.1 Connection Diagram of LM317 Regulator The typical connection diagram of LM317 regulator is shown in the Fig. 10.23.

LM3.1 7 package, typical circuit diagram (Courtesy : National Semiconductor Corp.) Three terminals of adjustable voltage regulators are Vin, Vout, and ADJUSTMENT (ADJ). Figure 16.25 shows atypical connection diagram for the LM317 regulator. From this diagram it is obvious that LM317 requires only two external resistors to set the output voltage. When configured as shown in this □MM figure the LM317 develops a nominal 1.25 V referred 2) Because of improved overload protection, greater load current can be drawn over the given operating temperature range. 3) Improved reliability for the power supply using these regulators. Thus, adjustable voltage regulators have become more popular because of their versatility, performance, and

reliability..The LM317 is the most widely used adjustable voltage regulator series. 5.13.1 Connection Diagram of LM317 Regulator The typical connection diagram of LM317 regulator is For this reason, I have designed an experimental, batterypowered circuit that can be used with resistorbypassed sensor switches. Figure 833 shows the circuit diagram. Figure 834 shows how the system is connected to a network of up to eight resistorbypassed sensor switches. The circuit is powered by a pair of 6volt lantern batteries connected in series. An LM317T voltage regulator is used to provide a steady output voltage of about 8.5 volts. This guarantees that the circuit will The regulator can accept a maximum voltage input of 40 V. The output

The output voltage is set by the value of the resistor R in the diagram below.

This is done by feeding the output of the first inverter to a second inverter, whose output represents ground for biasing the regulator. Figure 1 .

used.in this instrument include: Ul 74C14N CMOS Schmitt Trigger Hex Inverter; U2 LM317T variable voltage regulator; Ql IRF51 1 Nchannel If you are not using a metal enclosure for housing this project, then you should use a standard TO220 heatsink (Radio Shack #2761363 or similar) to directly mount the LM317T chip. All remaining wiring is rather straightforward and should pose little problem if you follow the schematic diagram in Fig. 171. Figure 172 shows the pinout This is necessary due to the design of the LM317T regulator which has an output voltage no less than 1.25 volts.
