On the datasheet it doesn’t mention an input voltage.

Voltage regulators basically can be divided in two big datassheet How much higher depends on the type of regulator. The current to your load flows through the regulator and is the same current as will be drawn from the input voltage.

Linear regulators are different. If you have an input voltage of 20V the same 1A will be drawn from that 20V.

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 A note on dissipation: 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. The datasheet does say how much it needs, but you may have to look for it. If we look further we can see two values for line regulation; it appears that this is best datasheey the input voltage is at least 16V.

EP Datasheet pdf – 78K/0 series emulation probe – NEC

On page 6 of the datasheet, the maximum dropout voltage Vd is listed as 2. Since the output is 12 volts, you add the two together to get a minimum input of But since there’s this voltage drop the input voltage has to be higher than the output voltage. This is a snapshot of page 8: Therefore it’s best to keep the input voltage just above the minimum to prevent the regulator to become overheated.

Peter Mortensen 1, 3 14 The maximum dropout voltage Vd is 2. That means that when your load consumes 10W the switcher will only dissipate 1W. This is a snapshot of page 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.

Dean 4, 22 57 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 does it go from a Maximum dropout voltage to a minimum input voltage? All linear regulators have a minimum dropout voltageor difference.

From what i understand then from your answer So if you have a 12W load it will draw 1A from the regulator. Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design. Home Questions Tags Users Unanswered. xatasheet

The is not a LDO low-dropout regulatoras the typical dropout voltage is around 2 volts. Sign up or log in Sign up using Google. The is a non-LDO linear regulator, which means it needs a higher input voltage.

The input voltage must be above the output. Sign up using Facebook.

So you won’t find a parameter “minimum input voltage”, but it is mentioned as a condition for proper operation within certain limits.
