The LM137H, manufactured by Motorola Semiconductor, is an adjustable 3-terminal negative voltage regulator. This component is designed to supply output currents of -1.5A or more, with an adjustable output voltage range from -1.25V to -37V. It requires only two external resistors to set the output voltage and one output capacitor for frequency compensation.
Key electrical characteristics include a typical line regulation of 0.01%/V and a typical load regulation of 0.3%. It also offers a typical ripple rejection of 77dB and a temperature coefficient of 50 ppm/°C. The device features internal current limiting, thermal overload protection, and safe-area compensation, making it robust against overloads.
The LM137H is available in TO-(3) and SOT-223 packages. The TO-(3) package has a body size of 8.255 mm x 8.255 mm, while the SOT-223 package measures 3.50 mm x 6.50 mm. These regulators are ideal complements to adjustable positive voltage regulators like the LM117 and LM317, finding applications in industrial power supplies, factory automation, and instrumentation devices.
