DESCRIPTION
The 137/337 Series regulators are adjustable 3 terminal voltage regulators capable of supplying in excess of -1.5A over an
output voltage range of -1.2V to -37V (HV Series, -47V). The regulators are exceptionally easy to apply requiring only 2 external
resistors to set the output voltage and 1 output capacitor for frequency compensation.
Every effort has been made to make these devices easy to use and difficult to damage. Internal current limiting and power
limiting coupled with true thermal limiting prevents damage due to overloads or shorts, even if the regulators are not fastened
to a heat sink.
