What is Optoelectronic Devices? Optoelectronics is the technology that combines optics and electronics and the devices based on this technology are known as optoelectronic devices. These devices include emitters, sensors…
Switch Mode Power Supply (SMPS) or Switching Regulators: Switch Mode Power Supply (SMPS) - The regulated power supplies described earlier were basically linear voltage regulators. A linear voltage regulator possesses…
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…
Shunt Voltage Regulator Block Diagram: A shunt voltage regulator provides regulation by shunting current away from the load. The block diagram of such a voltage regulator is depicted in Fig.…
Controlled Transistor Series Regulator or Negative Feedback Regulator: A controlled transistor series regulator is shown in Fig. 43.6. This Controlled Transistor Series Regulator circuit is quite similar to that of…
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…
