3 Description
The LM137 and LM337-N are adjustable 3-terminal negative voltage regulators capable of supplying
- 1.5 A or more currents over an output voltage range of
- 1.25 V to
- 37 V. It requires only two external resistors to set the output voltage and one output capacitor for frequency pensation. The circuit design has been optimized for excellent regulation and low thermal transients. Further, the LM137 and LM337-N feature internal current limiting, thermal shutdown and safe-area pensation, making it virtually blowout-proof against...
