What is Current Boosting in Voltage Regulator? Current Boosting in Voltage Regulator - IC723 regulator is limited to provide a maximum current of 140 mA. To increase its current capacity,…
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…
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.…
