The LM79LXXAC series of 3-terminal negative voltage regulators features fixed output
voltages of −5V, −12V, and −15V with output current capabilities in excess of 100mA. These devices
were designed using the latest computer techniques for optimizing the packaged IC
thermal/electrical performance. The LM79LXXAC series, when combined with a minimum output capacitor
of 0.1μF, exhibits an excellent transient response, a maximum line regulation of 0.07%
VO/V, and a maximum load regulation of 0.01%
VO/mA.
The LM79LXXAC series also includes, as self-protection circuitry: safe operating area
circuitry for output transistor power dissipation limiting, a temperature independent short circuit
current limit for peak output current limiting, and a thermal shutdown 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.
