Quality Control: Learn More
The STMicroelectronics LM137K is a negative adjustable linear voltage regulator designed for applications demanding robust performance. This TO-3 packaged component provides a stable output voltage ranging from -1.2V to -37V, with a maximum input voltage of 40V and capable of delivering up to 1.5A of output current. Key features include built-in overcurrent and overtemperature protection, ensuring reliability in demanding environments. The device offers significant power supply ripple rejection (PSRR) of 77dB down to 60dB across a frequency range of 120Hz. Its wide operating temperature range of -55°C to 150°C makes it suitable for use in industrial, automotive, and telecommunications sectors where precise and stable negative voltage regulation is critical.
