78012 DATASHEET PDF

Fekus Linear regulators are different. 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. Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design. This is a snapshot of page 8: So if you have a 12W load it will draw 1A from the regulator. If so, what is the current like that it outputs? 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. There are LDOs Low Drop-Out which still can regulate the output if the input is only a few hundreds of mV higher and there are even ultra low drop-out types which only need a few tens of mV.

That means that when your load consumes 10W the switcher will datasheet dissipate 1W. Voltage regulators basically can be divided in two big groups: Peter Mortensen 1, 3 14 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.

If we look further we can two values for line regulation; it appears that this is best if the input voltage is at least 16V. Sign up using Email and Password. The difference of 8W will be dissipated in datashfet regulator. The current to your load flows through the regulator and is the same current as will be drawn from the input voltage.

A note on dissipation: If so, what is the current like that it outputs? Email Required, but never shown. Even though the typical dropout voltage is 2 volts, you should use the maximum value in your design. Dean 4, 22 57 They are like a variable series resistor between input and output, causing a voltage drop across the regulator. How much higher depends on the type of regulator.

The is not a LDO low-dropout regulatoras the typical dropout voltage is around 2 volts. The input voltage must be above the output.

An LDO might have a dropout voltage of 0. Post as a guest Name. How does it go from a Maximum dropout voltage to a minimum input voltage? On page 6 of the datasheet, the maximum dropout voltage Vd is listed as 2. Linear regulators are different. This is a snapshot of page All linear regulators have a minimum dropout voltageor difference.
