## 7812CT Datasheet – 12V, Voltage Regulator

The datasheet does say how much it needs, but you may have to look for it. Home Questions Tags Users Unanswered. If you have an input voltage of 20V the same 1A will be drawn from that 20V.

So the 20V delivers 20W, while the load only datahseet 12W.

## 7812 12V 1A Voltage Regulator

Email Required, but never shown. A note on dissipation: The maximum dropout voltage Vd is 2. This is a snapshot of page If so, what is the current like that it outputs?

BS EN 558-2 PDF

Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design. Sign up using Facebook. If we look further we can see two values for line regulation; it appears that this is best if the input voltage is at least 16V.

The input voltage must be above the output. How does it go from a Maximum dropout voltage to a minimum input voltage? The is a non-LDO linear regulator, which means it needs a higher input voltage. On the datasheet it doesn’t mention an input voltage. Peter Mortensen 1, 3 14 Voltage regulators basically can be divided in two big groups: The is dayasheet a LDO low-dropout regulatoras the typical dropout voltage is around 2 volts.

That means that when your load consumes 10W the switcher will only dissipate 1W.

On page 6 of the datasheet, the maximum dropout voltage Vd is listed as 2. Dean 4, 22 57 The current to your load flows through the regulator and is the same current as will be drawn from the input voltage.

From what i understand then from your answer Post as a guest Name. A is a linear regulator, and does not step up the input voltage if the input is below the output for that you need a DC-DC boost regulator. How much higher depends on the type of regulator. Therefore it’s best to keep the input voltage just above the minimum to prevent the regulator to become overheated.

All 7812t regulators have a minimum dropout voltageor difference. They are like a variable series resistor between input and output, causing a voltage drop across the regulator.
