The LM137H from Thomson-CSF is an adjustable 3-terminal negative voltage regulator designed to supply currents of -1.5A or more. Its output voltage can be set from -1.25V to -37V using only two external resistors and an 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 features 77 dB of ripple rejection and a temperature coefficient of 50 ppm/°C. The device incorporates internal current limiting, thermal overload protection, and safe-area compensation, making it robust against overloads.
Available in TO-220-3 and SOT-223-4 packages, the LM137H is suitable for various applications including industrial power supplies, factory automation, and instrumentation devices. The TO-220-3 package has a body size of 8.255 mm x 8.255 mm, while the SOT-223-4 measures 3.50 mm x 6.50 mm.
