![]() The difference in the value of the input voltage and the output voltage comes as heat. In IC 7805 voltage regulator, lots of energy is exhausted in the form of the heat. ![]() The IC when given an input voltage of 7.2V, will achieve its maximum efficiency. Output polarity reversal protection circuitĪpply an unregulated voltage to get a regulated output.There are many application where 7805 play a very important role: One of the popular ICs for this purpose is 7805 Regulator IC, which is a member of fixed linear voltage regulators used to maintain such fluctuations.

In astable mode, the circuit of the IC produces a continuous pulse with exact frequency based on the value of the two resistors and capacitors which are connected in the external circuit.In monostable mode, the circuit generates only single pulse when the timer gets an indication from input of the trigger button.The output signals of low and high states signals are controlled by reset and activating the input pins. In bistable mode, the circuit produces 2-stable state signals that are in low and high states.There are three modes of operation of the Timer IC, which are bistable, monostable and astable mode. Open collector output to discharge capacitor Provides access to the internal voltage dividerĪcts as the threshold as to when to stop the timing interval Is driven to ~1.7V below Vcc or to ground ![]() The pin diagram of the 555 Timer IC is given below.
