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.
