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.
