Computer Block Diagram - PC Schematic
Here is a brief summary computer block

diagram of a typical Personal Computer.
The von Neumann (CISC) architecture employs a single bus. CISC stands for Complex Instruction Set Computer. A single-bus system is illustrated.

The Harvard (RISC) architecture utilizes two busses - a data bus and a separate address bus. RISC stands for Reduced Instruction Set Computer.
Relationships are shown between the CPU, DRAM, local bus, and the peripherals which connect to the motherboard. The ISA bus, SCSI Bus, PCI bus and USB Bus are shown. Some typical computer parameters are given, along with a Graphics Resolution chart.

voltage regulator lm7805

Voltage Regulator (regulator), usually having three legs, converts varying input voltage and produces a constant regulated output voltage. They are available in a variety of outputs.


The most common part numbers start with the numbers 78 or 79 and finish with two digits indicating the output voltage. The number 78 represents positive voltage and 79 negative one. The 78XX series of voltage regulators are designed for positive input. And the 79XX series is designed for negative input.

Examples:

· 5V DC Regulator Name: LM7805 or MC7805

· -5V DC Regulator Name: LM7905 or MC7905

· 6V DC Regulator Name: LM7806 or MC7806

· -9V DC Regulator Name: LM7909 or MC7909

The LM78XX series typically has the ability to drive current up to 1A. For application requirements up to 150mA, 78LXX can be used. As mentioned above, the component has three legs: Input leg which can hold up to 36VDC Common leg (GND) and an output leg with the regulator's voltage. For maximum voltage regulation, adding a capacitor in parallel between the common leg and the output is usually recommended. Typically a 0.1MF capacitor is used. This eliminates any high frequency AC voltage that could otherwise combine with the output voltage. See below circuit diagram which represents a typical use of a voltage regulator.
 
 
 

Note:


As a general rule the input voltage should be limited to 2 to 3 volts above the output voltage. The LM78XX series can handle up to 36 volts input, be advised that the power difference between the input and output appears as heat. If the input voltage is unnecessarily high, the regulator will overheat. Unless sufficient heat dissipation is provided through heat sinking, the regulator will shut down.

3-Terminal 1A Positive Voltage Regulator


General Description
The LM78XX series of three terminal positive regulators are

available in the TO-220 package and with several fixed output

voltages, making them useful in a wide range of applications.

Each type employs internal current limiting, thermal shut down

and safe operating area protection, making it essentially inde-

structible. If adequate heat sinking is provided, they can deliver

over 1A output current. Although designed primarily as fixed

voltage regulators, these devices can be used with external

components to obtain adjustable voltages and currents
 
 
Features

 Output Current up to 1A

Output Voltages of 5, 6, 8, 9, 12, 15, 18, 24

 Thermal Overload Protection

Short Circuit Protection

 Output Transistor Safe Operating Area Protection
