Onsemi LM337TG Adjustable Negative Voltage Regulator -1.2V to -37V 1.5A
Onsemi LM337TG adjustable negative voltage regulator with -1.2V to -37V output and 1.5A current, in a TO-220AB through-hole package.
The Onsemi LM337TG Adjustable Negative Voltage Regulator provides an adjustable negative output from -1.2V to -37V with up to 1.5A of output current, making it a versatile option for electronic designs.
Overview
The LM337TG requires only two external resistors to set the desired output voltage. This allows designers to set the output voltage without stocking multiple fixed voltage regulators. The device incorporates internal current limiting, thermal shutdown, and safe area compensation. It also includes internal thermal overload protection, short-circuit current limiting that remains constant with temperature, and output transistor safe area compensation.
