That means that when your load consumes 10W the switcher will only dissipate 1W. How does it go from a Maximum dropout voltage to a minimum input voltage?
The maximum dropout voltage Vd is 2.
So you won’t find a parameter “minimum input voltage”, but it is mentioned as a condition for proper operation within certain limits. If so, what is the current like that it outputs?

If you have an input voltage of 20V the same 1A will be drawn from that 20V. The datasheet does say how much it needs, but you may have to look for it. There are LDOs Low Drop-Out which still can regulate the output if the input is only a few hundreds datasheeg mV higher and there are even ultra low drop-out types which only need a few tens of mV. An LDO might have a dropout voltage of 0. From what i understand then from your answer This is a snapshot of page 8: Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design.

7812CT Datasheet – 12V, Voltage Regulator
Home Questions Tags Users Unanswered. A note on dissipation: So the 20V delivers 20W, while the load only consumes datasueet. On the datasheet it doesn’t mention an input voltage.
Voltage regulators basically can be divided in two big groups: Linear regulators are different. All parameters are specified under certain conditions, and for the output voltage we can see 78112ct the condition is that the input voltage is minimum But since there’s this voltage drop the input voltage has to be higher than the output voltage.
CT Datasheet – 12V, Voltage Regulator –
I’ve seen LDOs with a dropout voltage of 50 mV. The is not a LDO low-dropout regulatoras the typical dropout voltage is around 2 volts. All linear regulators have a minimum dropout voltageor difference. Peter Mortensen 1, 3 14 They are like a variable series resistor between input and output, causing a voltage drop across the regulator.
The difference of 8W will be dissipated in the regulator. Therefore it’s best to keep the input voltage just above the minimum to prevent the regulator to become overheated.

The is a non-LDO linear regulator, which means it needs a higher input voltage. 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.
The input voltage must be above the output. So if you have a 12W load it will draw 1A from the regulator.
