General Description
The LM79MXX series of 3-terminal regulators is available
with fixed output voltages of -5V, -12V, and -15V. These
devices need only one external component-a compensation capacitor at
the output. The LM79MXX series is packaged in the TO-220 power package,
and is capable of supplying 0.5A of output current.
These regulators employ internal current limiting, safe area
protection, and thermal shutdown for protection against virtually all overload
conditions.
Low ground pin current of the LM79MXX series allows output
voltage to be easily boosted above the preset value with a resistor divider.
The low quiescent current of these devices with a specified maximum change
with line and load ensures good regulation in the voltage boosted mode.
For output voltage other than -5V, -12V, and -15V
the LM137 series provides an output voltage range from -1.2V to -57V.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
