circuit to prevent excessive junction temperature.
Although designed primarily as fixed voltage
regulators, these devices may be combined with
simple external circuitry for boosted and/or adjustable
voltages and currents. The LM79LXXAC series is
available in the 3-lead TO package, the 8-lead SOIC
package, and the 6-Bump DSBGA package.
For output voltages other than the pre-set -5V, -12V
and -15V, the LM137L series provides an adjustable
output voltage range from -1.2V to -47V.
