What is the current rating of voltage regulator IC lm338k?
Here is the LM338 Adjustable DC power supply circuit, 1.2V to 30V. It can provide a current maximum to 5A and 10A.
What is the current rating of voltage regulator IC LM317L?
The LM317L is an adjustable 3−terminal positive voltage regulator capable of supplying in excess of 100 mA over an output voltage range of 1.2 V to 37 V.
Which regulator IC is variable regulator IC?
LM317 voltage regulator IC The adjustable pin (terminal) is provided with a variable resistor which lets the output to vary between a wide range.
How does an LM317 work?
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. The device features a typical line regulation of 0.01% and typical load regulation of 0.1%.
What is adjustable voltage regulator?
An adjustable voltage regulator produces a DC output voltage, which can be adjusted to any other value of certain voltage range. Hence, adjustable voltage regulator is also called as a variable voltage regulator. The DC output voltage value of an adjustable voltage regulator can be either positive or negative.
What is LM317 used for?
The LM317 serves a wide variety of applications including local, on card regulation. This device can also be used to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM317 can be used as a precision current regulator.
What is the input voltage range of IC 7805?
7V- 35V
Input voltage range = 7V- 35V.
What is the range of output voltage of LM337?
–1.2 V to –37 V
The LM237 and LM337 are adjustable 3-terminal negative-voltage regulators capable of supplying in excess of –1.5 A over an output voltage range of –1.2 V to –37 V.
What is adj in regulator?
ADJ The adjust pin is used to set the regulated output voltage by connecting it to the external resistors R1 and R2 (see TYPICAL APPLICATION CIRCUIT).
What is the difference between fixed voltage regulator and adjustable regulator?
Adjustable Voltage regulators require a very few external components to achieve its operation. Fixed voltage regulators require almost no external components (may be a couple of bypass capacitors). At low cost you have a wide range of voltage and current selection.
