What is LM337?

What is LM337?

LM337 ACTIVE 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. They require only two external resistors to set the output voltage and one output capacitor for frequency compensation.

What is use of IC LM337?

The LM337 is the equivalent counterpart of the LM317 Positive Voltage regulator. The IC commonly used in Adjustable Lab Voltage generators in combination with the LM317 IC. It can also be used as Current Regulators and negative voltage protection circuits, refer the datasheet linked below for application circuits.

What is the reference voltage for the LM317 voltage regulator?

This Current Regulator Calculator will work for all adjustable integrated circuit regulators with a reference voltage (V REF) of 1.25. For more information about these voltage regulators, see the LM317 / LM338 / LM350 Voltage Regulator Calculator, Information and Circuits page .

Which is the equivalent of the LM337 IC?

LT137, PB137, LM317 (Positive Variable Voltage regulator) The LM337 is the equivalent counterpart of the LM317 Positive Voltage regulator. The IC commonly used in Adjustable Lab Voltage generators in combination with the LM317 IC.

Is the lm334 a constant current source?

See Constant Current Circuits with the LM334. The next series of circuits will use the LM317. While designed as a variable voltage regulator, it will double as a stable constant current source. With only three pins as shown above, one can produce a current of about 1-amp max.

How to calculate the output current from a voltage regulator?

For more information about these voltage regulators, see the LM317 / LM338 / LM350 Voltage Regulator Calculator, Information and Circuits page . To determine the output current from the regulator, enter a value for the program resistor (R 1) in ohms and press the “Calculate” button.
