Frequently Asked Questions
What is the output voltage range of the LM137H?
The LM137H is an adjustable negative voltage regulator. By connecting an external resistor divider between the adjustment pin and output, users can set the output voltage from approximately -1.2V to -37V, making it highly flexible for various negative rail power supply designs.
What is the maximum input voltage for the LM137H?
The LM137H has a maximum input-output voltage differential of 40V. With a minimum differential of 3V (dropout voltage), it can handle input voltages up to 40V above the output voltage, supporting a wide range of power supply configurations in industrial and laboratory applications.
What package does the LM137H come in?
The LM137H comes in a TO-39 metal can package (JESD-30 code: O-MBCY-W3), a 3-pin hermetically sealed through-hole package well-suited for high-reliability and military-grade applications where thermal performance and mechanical robustness are critical.
Can the LM137H be used as a replacement for LM337?
Yes, the LM137H is functionally similar to the LM337 series and can serve as a direct replacement in many negative voltage regulator circuits. The LM137H is rated for operation over a wider temperature range, making it preferable for industrial or military environments compared to standard commercial LM337 variants.
