3-Terminal Adjustable Negative Regulator D337

DESCRIPTIONS：

The D337 are adjustable 3-terminal negative voltage regulators capable of supplying in excess of − 1.5A over an output voltage

range of − 1.2 V to − 37V. 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.

The D337 serve a wide variety of applications including local on-card regulation, programmable-output voltage regulation or

precision current regulation. The D337 is ideal complements to the D337 adjustable positive regulators.
