IC 79xx (, , , ) – Negative Voltage Regulator | TurboFuture

Usage of voltage regulator ICs helps in avoiding such events by maintaining voltage at the required levels. The main purpose of this IC is to supply required regulated negative voltage to the circuits. It is a small integrated circuit used in a circuit to supply a constant negative input voltage.

This supports the Maven widget and search functionality. You can also check on 78 series for positive voltage regulators. I have used a Battery to power the IC, but you can use any power source but notice that the supply voltage should be negative.

The pin 1 acts as the Ground terminal 0V. Regulahor order to improve stability two capacitors — C 1 and C 2 are used. The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter. The output current of this IC is upto 1A, however with appropriate heat sink the datasheet says that a peak current of 2. This is an ad network. We may use remarketing pixels from advertising networks such as Google AdWords, Bing Ads, and Facebook in order to advertise the HubPages Service to people that have visited our sites.


Values given may be increased without limit. Some articles have Google Maps embedded in them. IC 79xx is a three pin negative voltage controller IC. The Input and output capacitors C1 10uF degulator C2 1uF are rgeulator to filter noise from the input and the output voltage respectively.

IC 79xx can supply a constant negative voltage output, in spite of any voltage fluctuations in its input voltage. This is used to display charts and graphs on articles and the author center. Complete Technical Details can be found at the datasheet given at the end of this page. No data is shared with Paypal unless you engage with this feature. The number 79 indicates that it is a negative voltage regulator and xx indicates the output voltage of the IC.

IC 79xx requires heat sink for its safe operation. This is used to identify particular browsers or devices when the access the service, and is used for security reasons. Non-consent will result in ComScore only processing obfuscated personal data.

The pin 2 acts as the input terminal 5V to 24V. Available in TO package only.
