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…
Op Amp Regulators: The Op Amp Regulators which includes Op-Amp Series Voltage Regulator Circuit, Current Limiting circuit, Foldback Limiting and Op-Amp Shunt Voltage Regulator Circuit. Let us see one by…
Regulated and Unregulated Power Supply: Almost all electronic devices used in electronic circuits need a dc source of power to operate. The source of dc power is used to establish…
TTL Characteristics and other TTL Series: The first time standard TTL ICs were introduced by Taxas Instruments Corporation. They introduced 54 and 74 series, which were widely used as IC…
Integrated Injection Logic (IIL or I2L) Circuit: It is the latest entry into the bipolar saturated logic field. It uses no biasing and loading resistors at all. Resistors require lot…
What is Emitter Coupled Logic (ECL) Circuit? Emitter coupled logic (ECL) is the fastest of all logic families and, therefore, is employed in applications where very high speed is essential.…
What is a Digital Integrated Circuit? In an integrated circuit, components such as diodes, transistors, resistors, inductors etc. are integral parts of the chip. And on surface of this chip,…
