There are several factors that affect the heat output of a voltage regulator. A linear regulator such as a 7805 series will pass the same amount of current as the load draws. The regulator will also have a certain voltage across it and can be calculated by subtracting the output voltage (5V in this case) from the source voltage. The source voltage might be anywhere from 7 volts up to as much as 30 volts.
The heat generated in the regulator can be calculated using the power equation, power = current x voltage. As stated above, the current is dependant on the load. As the current increases, so the power dissipated in the regulator increases. Similarly, as the source voltage increases, so does the power dissipated by the regulator.
The regulator will always show a temperature rise but how hot it gets depends on how effectively the heat is drawn away from the regulator. If the regulator is mounted on an effective heat sink, it can dissipate large amounts of heat without becoming hot. Without a heatsink, the same regulator in the same situation will become far hotter.
All regulators have certain limits for power dissipation and temperature. The data sheet will have information on the limits and they should always be noted during a design phase.
Some simple 3 terminal single chip linear regulators are:+5V - 7805, LM309, LM323-5V - 7905, LM320Some high efficiency single chip switching regulators are: +5V - LM2574-5.0, LT1076-5-5V - LT3015-5Note: always read the datasheet carefully to make sure a part meets the requirements of your application before designing around the part.
No, you cannot put two 5V voltage regulators in series to obtain 10V. Voltage regulators are designed to maintain a constant output voltage regardless of the input voltage, and connecting them in series would not sum their outputs as you might expect. Instead, it could lead to instability or damage to the regulators. To achieve 10V, it's better to use a step-up (boost) converter or a dedicated 10V regulator.
5v
5V
It is depend on your requirement .suppose you need a voltage regulator of 5V than you need 5V Zener diode.

Billy the kid was in a group called the Regulators. They were a group of outcasts like Billy who wanted to be "cowboys". The Regulators always had each others backs.
By changing the polarity of the source
The answer is 1 + 5v.
By changing the polarity of the source

yes
Who are the regulators in the Carolinas were?
5v
+12V, -12V, +5V, -5V, +3.3V -5V is seldom used
