The LM137 are adjustable 3-terminal negative
voltage regulators capable of supplying in excess of
-1.5A over an output voltage range of -37V to -1.2V.
These regulators are exceptionally easy to apply,
requiring only 2 external resistors to set the output
voltage and 1 output capacitor for frequency
compensation. The circuit design has been optimized
for excellent regulation and low thermal transients. …
