Application & Notes
LM137K by STMicroelectronics is a power conversion IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 40V, output -1.2V. The TO-204AA, TO-3 package with surface mount mounting is standard for compact designs. Pay attention to input/output capacitor selection and PCB layout — switching regulators are sensitive to trace inductance.
