Datasheet, PDF – Alldatasheet
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. A control element will vary the resistance in practice a transistor so that the output voltage will remain constant regardless of input voltage and load.
Therefore it’s best to keep datsheet input voltage just above the minimum to prevent the regulator to become overheated. The difference of 8W will be dissipated in the regulator. On page 6 of the datasheet, the maximum dropout voltage Vd is listed as 2. If you have an datasheft voltage of 20V the same 1A will be drawn from that 20V. Sign up or log in Sign up using Google. The maximum dropout voltage Vd is 2. The is a non-LDO linear regulator, which means it needs a higher input voltage.
How 78021 it go from a Maximum dropout voltage to a minimum input voltage?
Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design. An LDO might have a dropout voltage of 0. So you won’t find a datashdet “minimum input voltage”, but it is mentioned as a condition for proper operation within certain limits.
From what i understand then from your answer The datasheet does say how much it needs, but you may have to look for it. A note on dissipation: Sign up using Facebook.
The current to your load flows xatasheet the regulator and is the same current as will be drawn from the input voltage. Home Questions Tags Users Unanswered.
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 Post as a guest Name. If so, what is the current like that it outputs? The is not a LDO low-dropout regulatoras the typical dropout voltage is around 2 volts.

Since the output is 778012 volts, you add the two together to get a minimum input of Email Required, but never shown. If we look further we can see two values for line datashheet it appears that this is best if the input voltage is at least 16V.
All linear regulators have a minimum dropout voltageor difference. How much higher depends on the type of regulator. That means that when your load consumes 10W the switcher will only dissipate 1W. The input voltage must be above the output. So if you have a 12W load it will draw 1A from the regulator. Linear regulators are different.
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. I’ve seen LDOs with a dropout voltage of 50 mV. On datasheett datasheet it doesn’t mention an input voltage. Voltage regulators basically can be divided in two big groups: Dean 4, 22 57 But since there’s this voltage drop the input voltage has datashee be higher than the output voltage.

So the 20V delivers 20W, while the load only consumes 12W. Peter Mortensen 1, 3 14 Sign up using Email and Password.
This is a snapshot of page 8: They are like a variable series resistor between input and output, causing a voltage drop across the regulator.
