What is the current rating of voltage regulator ic lm338k

The LM317L device is a 100-mA linear regulator with high voltage tolerance up to 35 V.

What is the current voltage regulator?

A voltage regulator is a circuit that creates and maintains a fixed output voltage, irrespective of changes to the input voltage or load conditions. Voltage regulators (VRs) keep the voltages from a power supply within a range that is compatible with the other electrical components.

What is LM317 voltage regulator?

The LM317 device is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It requires only two external resistors to set the output voltage.

What is the maximum current rating for a typical 7812 IC?

Description. The 7812 is a fixed voltage linear regulator that can output 12V at up to 1A current with an input voltage range of 14 – 35V.

What is regulator current?

A current regulator is an integrated circuit that provides a constant current regardless of changes in the input voltage or load current. It is based on self-biased transistor technology and regulates current over a range of voltages.

Does a voltage regulator regulate current?

Although it has to be said that voltage regulators usually do control the current, i.e. they have a built-in current-limiting circuit, and they have a thermal shutdown circuit, and thus they don't normally get damaged by a short circuit on the output.

What is voltage regulator formula?

The circuit diagram of a voltage regulator using a Zener diode is shown: The value of the series resistor is written as RS = (VL − VZ)IL. Current through the diode increases when the voltage across the diode tends to increase which results in the voltage drop across the resistor.

How many amps is LM317?

The LM317 is an adjustable 3−terminal positive voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of 1.2 V to 37 V.

Can LM317 sink current?

It can sink constant currents of 100mA, 200mA, 500mA or 1A, selected by a rotary switch. Officially the minimum input voltage is 4V, but in reality the current remains constant down to an input voltage of 3.6V. The maximum input voltage is 35V as long as you provide adequate cooling for the LM317.

How do you calculate current output in LM317?

The LM317 is also suitable as a simple constant current source. The voltage regulator is adjusted so that between Adj and Vout is 1.25 volts. Therefore, I = 1.25 / R1, the maximum current can be calculated. The output current can be between 0.01 and 1.25 amperes (R1 between 1 and 120 ohms).

What is maximum regulator current?

The maximum current is calculated by dividing the power rating by the Zener voltage: I=P/V = 3W/12V = 0.25A.

How do you calculate maximum current rating?

Find out the power rating of the resistor, the maximum current is (square root of power)/resistance .
