Some simple 3 terminal single chip linear regulators are:

  • +5V - 7805, LM309, LM323
  • -5V - 7905, LM320
Some high efficiency single chip switching regulators are:
  • +5V - LM2574-5.0, LT1076-5
  • -5V - LT3015-5

Note: always read the datasheet carefully to make sure a part meets the requirements of your application before designing around the part.

What is an 7805 regulator?

7805is a voltage regulator integrated circuit. It is a member of 78xx series of fixed linear voltage regulator ICs. The voltage source in a circuit may have fluctuations and would not give the fixed voltage output. The voltage regulator IC maintains the output voltage at a constant value. The xx in 78xx indicates the fixed output voltage it is designed to provide. 7805 provides +5V regulated power supply. Capacitors of suitable values can be connected at input and output pins depending upon the respective voltage levels.Pin Diagram:Pin Description:Pin NoFunctionName1Input voltage (5V-18V)Input2Ground (0V)Ground3Regulated output; 5V (4.8V-5.2V)Output

What is voltage stabilizer and what's it's control system circuit?

Voltage stabilizers are the circuits that are used to filter noise from the source voltage. DC voltage generated from a bridge network or diode network will contains voltage glitches. These glitches may cause serious problems to the operation of digital circuits. So a voltage regulator is used to filter these glitches. voltage stabilizer can be built using a voltage regulator ICs like 7805 for +5V, 7809 for +9V, 7905 for -5V, 7909 for -9V and so on.
