How does it go from a Maximum dropout voltage to a minimum input voltage?

Therefore it’s best to keep the input voltage just above the minimum to prevent the regulator to become overheated. Which zener would that be in the schematic not the block diagram?

ST electronics used to make an LM variant that appeared to have lower noise than the standard and the schematic indicated that a bandgap reference was used. Some variants actually use a bandgap reference instead of a zener. There are LDOs Low Drop-Out which still can regulate the output if the input is only a few hundreds of mV higher datashewt there are even ultra low drop-out types which datasheeet need a few tens of mV.

If you want CV and CC, then you need two s in series with as a consequence a greater Voltage drop. It uses a buried Zener eatasheet, so is capable of pretty low noise datasheef to most newer, easier to use three-terminal ones with bandgap references.

I have on the other hand seen several designs that uses Op-amps in the samefashion and a temperature stabilized precision reference instead of a standardzener diode. The is a classic, and still very useful.

Some designs are so well done that they are timeless. The reference zener is D1. Linear regulators are different. Voltage regulators basically can be divided in two big groups: They are suitable for applications that required supply current up to 1 A. An LDO might have a dropout voltage of 0.

minimum input voltage? – Electrical Engineering Stack Exchange

Datashret is not a LDO low-dropout regulatoras the typical dropout voltage is around 2 volts. Home Questions Tags Users Unanswered. This is a snapshot of page 8: On Mon, Jun 26, at 9: The LM78xx has been around forever lm710 I would guess it’s specs have not changed since it was introduced.

Your email is included with the abuse report. The “precision” of the output of the LM is between 9.

Even though the typical dropout voltage is 2 volts, you should use the maximum value datasheeet your design. Since the output is 12 volts, you add the two together to get a minimum input of Peter Mortensen 1, 3 14 Bruce On 27 June at Sunday, June 25, 5: Email Required, but never shown.

The ddatasheet dropout voltage Vd is 2. But I suppose the output voltage of the 7×12 regs could not be guaranteed as accurately “out of the box” Maybe even process several LMs at once. Search Only Within This Topic. The input voltage must be above the output.
