How to use 78L There’s no sense in trying to get closer than that. In our case the 78L05 IC is an iconic regulator IC that finds its application in most datssheet the projects.

Since these regulators protect themselves from output shorts, there is effectively no upper limit from the regulator’s point of view.

On the output, TI states: The fast diode in Figure 15 shunts most of the capacitors discharge current around the regulator.

You mean tantalum type?

Better than 3 capacitors in parallel. Did I get you correct?

Sign up using Facebook. The 78L05 is a three terminal voltage regulator. When using large capacitors at the output of these regulators, a datasheett diode connected input to output Figure 15 may be required if the input is shorted to ground. Also note the Capacitors C1 and C2 are used at both the Input and output end.

In that using a high current regulator like would be an ideal choice. No, I mean caps with 0 ESR. Of course lm87l12 is no such thing, but some technologies, like ceramic, have low ESR with large enough values to be useful in this application. LM voltage regulator is recommended to be used with decoupling capacitors at its input and output as in the below diagram:.

You have to look elsewhere in the datasheet to find the min and max allowed values. Alternative Regulator for 78L Trevor Oh never thought of it. The capacitor will then discharge through a large internal input to output diode and parasitic transistors.

The Fairchild datasheet is limited to just data, with minimal application guidance. So you if connect high current loads then you can expect the IC to datawheet very hot soon and shunt down eventually.

The output current of this IC can go up to mA. From Texas Instruments datasheet:.

Do you have any idea about it? Those values are really the recommended minimums. The regulated 5V can be obtained from the output pin if the IC. I have two questions: Trevor I put 0. Because the maximum current that this IC could supply is only lm87l12 mA. But 1u already does the job of n.
