ONSEMI LM337BTG Negative Voltage Regulator

The LM337BTG is an adjustable three-terminal negative voltage regulator capable of outputting over 1.5A with a voltage range from -1.2V to -37V. It is easy to implement, requiring only two external resistors to set the desired output voltage. The device features internal protections such as current limiting, thermal shutdown, and safe area compensation, making it highly reliable and resistant to failure. Suitable for various applications including local or on-card regulation, it can also be configured as a programmable or a precision current regulator by connecting an additional resistor. The regulator supports floating operation for high-voltage applications and reduces the need for stocking multiple fixed-voltage regulators. It is ideal for industrial and power management applications.
