Description

LM337  Adjustable Negative Voltage Regulator

The  LM337  are adjustable 3-terminal negative voltage regulators capable of supplying  −1.5 A or more currents over an output voltage range of −1.25 V to −37 V.

They are easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators. Also, LM337 regulators are supplied in  TO-220 packages which are easily mounted and handled.

the LM337  series offers full overload protection available only in integrated circuits and features internal current limiting, thermal shutdown, and safe area compensation, making it virtually blowout-proof against overloads.

The LM337 is  commonly used in Adjustable Lab Voltage generators.  It can also be used as Current Regulators and negative voltage protection circuits.

The LM337 is a three-pin IC.

Pin 1 (Adjust): This pins adjusts the output voltage.
Pin 2 (input voltage): The input voltage which has to be regulated is given to this pin.
Pin 3 (Output Voltage): The regulated output voltage set by the adjust pin can be obtained from this pin.
