Foldback Current Limiting Circuit: The disadvantage of constant current limit is relatively large power dissipation in the series pass transistor when the load terminals are shorted. Thus a large power…
Constant Current Limiting Circuit: A block of series regulation using simple Constant Current Limiting Circuit is shown in the Fig. 2.119. It is also called short circuit protection circuit as…
Crystal Oscillators - Circuit, Working, Advantages and Disadvantages: In crystal oscillators, the usual electrical resonant circuit is replaced by a mechanically vibrating crystal. The crystal (usually quartz) has a high…
What is Dual Power Supply? -Circuit Diagram and its Workings? Many discrete and ICs need bipolar (dual power supply or ± V) supplies. This can be easily accomplished with two…
What is Current Foldback? The current limiting technique maintains a constant load current at some specified value and under overload condition, the Vout drops to zero. But, in case of…
What is Current Limiting Protection? The circuit arrangement for IC 723 as low voltage or high voltage regulator has no protection. If short circuiting takes place (when load demands more…
Controlled Transistor Series Regulator with Short Circuit Protection: Controlled Transistor Series Regulator with Short Circuit Protection - If the load resistance RL is reduced or load terminals are shorted accidentally,…
Transistor as an Amplifier - Circuit Diagram and Its Workings: The main utility of a transistor lies in its ability of amplifying weak signals. The weak signal is applied at…
