Buy it now – Add to Watch list Added to your Watch list. However, we think it necessary to inform our readers about fundamental faults and errors of electronics components that can cost a lot of time.

Again, we do apologize to GM Electronic for releasing this information. Add to Watch list Watching. In the LM datasheet by the same company, minimal load current is specified see picture below. Brief Description on Voltage Regulator Voltage regulators are very common in electronic circuits. In many cases where an Op-Amp is working in dual mode power supply a negative voltage will be regulated by these 79XX ICs. Output VA characteristics of a L So, keep this possibility in mind when designing your own applications.

Voltage regulators (stabilizers) 78xx and 79xx

If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. Figure datashet dependence of the output voltage on the input voltage for a L and a MC with no load, and with approx. See all condition definitions – opens in a new window or tab If ST really does use such an internal structure, the problem is most dagasheet caused by unsuitable values of resistors around the 6. However, components by other manufacturers behave differently.


See other items More Complete Technical Details can be found at the LM voltage regulator datasheet given at the end of this page.

As a preface, I would like to say that HW server does not indend at all to ‘criticise at every cost’. Seller’s payment instructions We are delighted to offer a no-fuss returns policy. Otherwise, their input voltage decreased by about 8V appears darasheet at the output.

Seller information spiratronics Well, I bought a new L by ST. Pay one price regardless of how many items you purchase from us. The items this applies to are clearly marked in the postage table. The negative voltage was used to power operational amplifiers on a second board as well. In most cases, only a single sample of a given type by a given manufacturer was available; datashfet are MC 3 samples measured and, of course, stabilizers by ST 5 samples of each type measured; samples purchased at different times in different stores.

LM Negative Voltage Regulator Pinout, Specs, Circuit & Datasheet

Unfortunately, we could not get a sample to measure. Please enter a number less than or equal to Input voltage 26V DC.


The 79xx voltage regulators daatsheet made by ST have to be connected to a load consuming at least 5 mA. The situation is similar with other stabilizers.

Here, minimum load current is specified: Also they should be of ceramic type, since ceramic capacitors are faster than electrolytic.

Voltage regulators (stabilizers) 78xx and 79xx |

Please note the differences in internal sctructure. Values shown were measured for a single sample; other samples as well as stabilizers by other manufacturers behaved similarly.

In our case the IC is an negative 5V regulator, meaning it provides -5V as output. This is true, BUT:.

Place an order before 3pm and have it shipped the same day. They provide a constant output voltage for a varied input voltage.

A 1A fixed regulator in an industry standard T package. Pay our low rate postage on the first item you purchase and the postage cost of every additional item you purchase from our shop is completely FREE.

Please enter up to 7 characters for the postcode. We have tried several different capacitors ranging from 15 nF to 1 uF, measured values were not significantly affected. The ST company can argue that this is possible; however, that the voltage from
