Description

LM7905: Fixed Three terminal Negative Voltage Regulator. The LM7905 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 LM7905 series is packaged in the TO-220 power package and is capable of supplying 1.5A 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 LM7905 series allows output voltage to be easily boosted above the preset value with a resistor divider. The low quiescent current drain of these devices with a specified maximum change with line and load ensures good regulation in the voltage boosted mode. For applications requiring other voltages, see LM137 datasheet. Features • Thermal, short circuit and safe area protection • High ripple rejection • 1.5A output current • 4% tolerance on preset output voltage
