The current to your load flows through the regulator and is the same current as will be drawn from the input voltage. I’ve seen LDOs with a dropout voltage of 50 mV. Post as a guest Name. A note on dissipation: Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design. Email Required, but never shown. The maximum dropout voltage Vd is 2.

7812 12V 1A Voltage Regulator
From the above it may look like you best make your input voltage a lot higher than the 12V output, but that’s not true. An LDO might have a dropout voltage of 0. If you have an input voltage of 20V the same 1A will be drawn from that 20V. On the datasheet it doesn’t mention an input voltage.
CT Datasheet – MCCT –
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. If we look further we 7182ct see two values for line regulation; it appears that this is best if the input voltage is at least 16V.
Peter Mortensen 1, 3 14 daatasheet The is not a LDO low-dropout regulatoras the typical dropout voltage is around 2 volts. On page 6 of the datasheet, the maximum dropout voltage Vd is listed as 2. All linear regulators have a minimum dropout voltageor difference.
Voltage regulators basically can be divided in two big datasjeet Sign up using Email and Password. The is a non-LDO linear regulator, which means it needs a higher input voltage. How does it go from a Maximum dropout voltage to a minimum input voltage? All parameters are specified under certain conditions, and for the output voltage we can see that 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.
minimum input voltage? – Electrical Engineering Stack Exchange
They are like a variable series resistor between input and output, causing a voltage drop across the regulator. This is a snapshot of page Home Questions Tags Users Unanswered.
If so, what is the current like that it outputs? How much higher depends on the type of regulator. The datasheet does say how much it needs, but you may have to look for it.
So you won’t find a parameter “minimum input voltage”, but it is mentioned as a condition for proper operation within certain limits. So if you have a 12W load it will draw 1A from the regulator.
