If you've used an LM7805 in another project, then an LM2940CT5 will seem perfectly familiar: it's in the same physical package, it has the same pinout, and you can drop it directly into a circuit where you would normally use an LM7805 and it will simply work. Reference schematics for the LM7805 abound If you want to draw larger currents for applications like driving motors, you may need to use voltage regulators like that in Figure 47. You can build this directly on a breadboard or you can purchase a “breadboard power supply stick 5 V/3.3V” from SparkFun (www.sparkfun.com() for about $15. (a) (b) As shown in Figure 47, the pin on the left of the regulator.is the voltage supply input. When delivering a current of 500mA, the KA7805/LM7805 voltage regulator will accept an input 8.4.1 Linear voltage regulators The simplest and most common method to achieve voltage regulation is by adding a device called a linear voltage regulator, an 1C containing all the circuitry necessary to implement the control function outlined in Fig. 8.11. The word To consider a specific example, Table 8.1 shows some values for the main performance parameters for a typical 7805 regulator, a common type of fixed + 5 V regulator which is produced by a number of manufacturers. mcd) red jumbo lightemitting diode (300 mcd) 1 highoutput infrared LED Diodes 4 in 4004 diodes (1 amp) Photoresistors Cadmium Sulfide.(Cds) photoresistors 5 in a package Transistors 1 3904 NPN silicon transistor 1 NPN silicon infrared photo transistor Photovoltaic Cells 1 silicon solar cell Integrated Circuits 1 7805 voltage regulator (1 amp) 1 7812 voltage regulator (1 amp) 1 — LM 3 1 7 voltage regulator 1 74LSOOTTL 1C 1 — 555 tinier These tour stages (including A voltage regulator is a device for converting an input voltage to a different output voltage. The one most commonly used in logic circuits is the 7805. This device takes a high input voltage, say 12 V, and regulates it down to give a 5 V output. The 7805 also removes any ripple or noise on the input line, and thus it is not just simply a potential divider circuit. Figure 2.30 shows a 7805 in.operation. The input and output capacitors (22 uF 'tants' are often used) are present to smooth the On card regulators. KIT INCLUDES ALL PARTS AND SOCKETS (except 2708 s).
