LM7905CT Description
These devices need only one external component—a compensation capacitor at the output. The LM7905CT 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.
The low ground pin current of the LM7905CT series allows the 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.
LM7905CT Features
• Thermal, short circuit, and safe area protection
• High ripple rejection
• 1.5A output current
• 4% tolerance on preset output voltage

Frequently Asked Questions
1.What is the output voltage of an lm7905 negative voltage regulator?
So our 7905 will provide a -5V output voltage. The output current of this IC can go up to 1.5A, but the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current. For example, if the input voltage is 12V and you are consuming 1A, then (12-5) * 1 = 7W.
2.What is the output voltage of a LM79xx regulator?
General Description. The LM79XX 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 LM79XX series is packaged in the TO-220 power package and is capable of supplying 1.5A of output current.
3.What kind of voltage regulator does a 7905 IC have?
LM7806, LM7809, LM7812, LM317, LM7805, LM7912, LM117V33, XC6206P332MR. Voltage regulators are very common in electronic circuits. They provide a constant output voltage for a varied input voltage. In our case the 7905 IC is a negative 5V regulator, meaning it provides -5V as output.
4.What's the difference between a 7905 and a 05?
The name 7905 signifies two meanings, “79” means that it is a negative voltage regulator and “05” means that it provides 5V as output. So our 7905 will provide a -5V output voltage.
5.Can a 7905 be used as a heat sink?
So our 7905 will provide a -5V output voltage. The output current of this IC can go up to 1.5A, but the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current. For example, if the input voltage is 12V and you are consuming 1A, then (12-5) * 1 = 7W. This 7 Watts will be dissipated as heat.
