Older instruments often use linear PSUs. On Mon, Jun 26, at 9: If you have an input voltage datashet 20V the same 1A will be drawn from that 20V.

All linear regulators have a minimum dropout voltageor difference. Subject of the new topic: They are suitable for applications that required supply current up to 1 A. Jun 26, That is not correct, the uses a surface zener, and is fairly noisy. Price is reasonable and they can do floating regulation.

This is a snapshot of page Regarding linear power supplies Some designs are so well done that they are timeless. That’s significantly better than a lot of ‘precision’ volt references. I prefer it to l7m810 anything else for positive supplies up to mA, for low noise analog and digital circuits.


Jim Thompson may have designed some of the different versions. How much higher depends on the type of regulator. Sign up using Facebook.

Bruce On 27 June at By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. But since there’s this voltage drop the input voltage has to be higher than the output voltage.

The same process can work with the LM for more current as they also have a negative tempco viz. What was the part number? From what i understand then from your lm77810 I’ve seen LDOs with a dropout voltage of 50 mV.

The is a non-LDO linear regulator, which means it needs a higher input voltage. It does take more parts to implement small regulators, so it depends on the application.

Your email is included with the abuse report. This is a snapshot of page 8: I still have a fair amount of work to do to qualify my process, but I hope to provide a DIY kit to deliver the capability to profile the voltage regulator and supply the required component values to make the precision hold over the temp.

Dean 4, 22 57 On Sunday, June 25, 4: Hi David, It would be interesting to know which devices you were testing at the time. On 27 June at Saturday, June 24, 3: I say “finally” because it has been going strong since when I first used it.

That means that when your load consumes 10W the switcher will only dissipate 1W. But I suppose the output voltage datssheet the 7×12 regs could not be guaranteed as accurately “out of the box” Recently acquired a precision Dekavider and a commercial precision voltage reference ADBQ based for ensuring reliable results.

There is no bandgap reference.

LM datasheet & applicatoin notes – Datasheet Archive

Inserting a diode to prevent back-current flow in series daatsheet V CC or bypass diodes between V CC and each pin is recommended. Damage to the internal circuit or element may occur when the polarity of the V CC pin is opposite to that of. 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 original Fairchild datasheet from the ‘s showed a zener reference was used.

They are suitable for applications that required.
