This is a snapshot of page 8: Post as a guest Name.

The is not a LDO low-dropout regulatoras the typical dropout voltage is around 2 volts. 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.

Linear regulators are different. The datasheet does say how much it needs, but you may have to look for it.

Sign up using Email and Password. 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 How does it go from a Maximum dropout voltage to a minimum input voltage?

Voltage regulators basically can be divided in two big groups: They are like a variable series resistor between input and output, causing a voltage drop across the regulator. Peter Mortensen 1, 3 14 The is a non-LDO linear regulator, which means it needs a higher input voltage.

The maximum dropout voltage Vd is 2.

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

If so, what is the current like that it outputs? The current to your load flows through the regulator and is the same current as will be drawn from the input voltage. Since the output is 12 volts, you add the two together to get a minimum input of By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

The difference of 8W will be dissipated in the regulator.

An LDO might have a dropout voltage of 0. Dean 4, 22 57 Email Required, but never shown. All linear regulators have a minimum dropout voltage datasheeg, or difference. This is a snapshot of page Therefore it’s best to keep the input voltage just above the minimum to prevent the regulator to become overheated. If you have an input voltage of 20V the same 1A will be drawn from that 20V.

If we 8712ct further we can see two values for line regulation; it appears that this is best if the input voltage is at least 16V.

How much higher depends on the type of regulator.
