The SR from Datel is a full switching power supply module designed as a drop-in replacement for 78xx chipsand not a linear regulator like the 78xx ICs. The circuit diagram for those can be found at the datasheet given at the end of this page.

LM 7912 CT

Retrieved from ” https: Meaning it will provide a constant output voltage of V when the input voltage is between Wikimedia Commons has media related to 78xx Series and Voltage regulator circuits.

From Wikipedia, the free encyclopedia. This article needs additional citations for verification. The 78xx line are positive voltage regulators: This page was last edited on 5 Decemberat Views Read Edit View history. The negative output voltage is obtained from the Vo 3rd Pin which is also read using a Multimeter.


There is a related line of 79xx devices which are complementary negative voltage regulators. Industrial Electronics and Control. You can also check on 78 series for positive voltage regulators. The value of the capacitors need not be the exact values, you can use the closest value you have got. In other projects Wikimedia Commons.

LM Applications Dataaheet V output regulator to use as power or reference voltage for analog and digital circuits. The output current of this IC is upto 1A, however with appropriate heat sink the datasheet says that a peak current of 2. The is the most common, as its regulated 5-volt supply provides a convenient power source for most TTL components.

TL — Programmable Reference Voltage. The Input and output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively. Available in TO package only.


When you are designing an analog circuitthe circuit might need negative voltage either as a power source or as a reference voltage. Encyclopedia of Electronic Components Volume 1: It is a component in switching regulator designs and is not a linear regulator like other 78xx devices. Complete Technical Details can be found at the datasheet given at the end of this page.

In both cases will be an ideal choice lm79912 you need a negative 12V. Submitted by webmaster on 23 November A very basic Voltage regulator circuit is shown below. Cool Projects for Open Source Hardware. Some devices provide slightly different voltages than usual, such as the LM78L62 6.

LM belongs to the family of Voltage regulators. Hence, I have interchanged the polarity of the battery. Mastering the Raspberry Pi.
