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…
LM340 Series Voltage Regulator: This LM340 Series Voltage Regulator is typical of the three-terminal voltage regulators. The block diagram is shown in Fig. 43.27. The built-in reference voltage Vref drives…
Adjustable Voltage Regulators: Sometimes variable voltage is required and under such a situation adjustable voltage regulators is used. A number of IC regulators, like LM317, LM338, and LM350, are adjustable…
Fixed Negative Voltage Regulator: As we have seen many times previously, positive and negative regulated power supply voltages are often required. In response, many manufacturers have developed negative three-terminal regulators.…
Fixed Positive Voltage Regulators: The series 7800 regulators provide eight voltage options, rangÂing from 5 to 24 V, as indicated in Table 43.2. These ICs are designed as fixed voltage…
Three Terminal IC Voltage Regulators - Block Diagram: The latest generation of IC voltage regulators has devices with only three pins: one for the unregulated input voltage, one for the…
IC Voltage Regulators: IC voltage regulators are versatile and relatively inexpensive and are available with features such as a programmable output, current-voltage boosting, internal short-circuit current limiting, thermal shutdown, and…
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…
