The 78L05 is a three terminal voltage regulator. As the TI datasheet says 0. Submitted by webmaster on 14 December The three terminals are Input, Output and ground lm78l1 shown in the 78L05 pinout diagram.

Did I get you correct? Some low ESR caps km78l12 parallel with some bulk 10uF caps won’t hurt. If the energy released by the capacitor is large enough, this diode, low current metal, and the regulator are destroyed. If the device is more than daatasheet inches from the input filter capacitors, an input bypass capacitor, 0.

Alternative Regulator for 78L Because the maximum current that this IC could supply is only upto mA.

So, if you are looking for a smaller package of voltage regulator that has small current rating in TO package then this IC might be the right choice. No, I mean caps with 0 ESR. Since these regulators datssheet themselves from output shorts, there is effectively no upper limit from the regulator’s point of view. You see them in parallel because different cap types have different high frequency characteristics.

TL — Programmable Reference Voltage. Sign up using Email and Password. The output current of this IC can go up to mA. What you quote doesn’t say what Co needs to be, only what value the rest of the specs are for.

Home Questions Tags Users Unanswered. I’m not sure those are exactly recommended values.

But 1u already does the job of n. Better than 3 capacitors in parallel.

CI is required if regulator is located an appreciable distance from the power supply filter. StainlessSteelRat 3, 6 Post as a guest Name. But what if I use a single 0.

In fact, the lower the better. In that using a high current regulator like would be an ideal choice. In the circuit below a input voltage of 12V is regulated to 5V using the 78L Complete Technical Details can be found at the 78L05 datasheet given at the end of this page.

It really does not matter much. LM voltage regulator is recommended to be used with decoupling capacitors at its input and output as in the below diagram:.

Another thing I never dataasheet sometimes they put decoupling caps for power rails in parallel like 1u and n ect. The regulated 5V can be obtained from the output pin if the IC. Olin Lathrop k 30 Also note the Capacitors C1 and C2 are used at both the Input and output end. It is very easy and straight forward to use this IC, just connect the input in to the input voltage which has to be regulated and the ground pin to system ground.

On the output, TI states: If I remember right your job to checkthe 78xx series regulators are stable with 0 ESR output caps.

The only ln78l12 limitation is therefore the initial surge current as the output cap is charged up. The Fairchild datasheet is limited to just data, with minimal application guidance.

When using large capacitors at the output of these regulators, a protection diode connected input to output Figure 15 may be required if the input is shorted to ground.

There’s no sense in trying to get closer ddatasheet that. The capacitor will then discharge through a large internal input to output diode and parasitic transistors. Apart from using it as a voltage regulator it can also be used as a current regulator, short-circuit protector, booster circuit and even a variable voltage regulator.
