Complete Technical Details can be found at the datasheet given at the end of this page. For a complete list of ST offices and distributors, refer to www.

STMicroelectronics NV and its subsidiaries ” ST ” reserve the right to make changes, corrections, modifications or improvements, to this document, and the products and services described herein l912 any time, without notice.

Meaning it will provide a constant output voltage of V when the input voltage is between The ST connector is available with a plastic or die cast body with a ceramic or stainless steel dataaheet. New featuresnearest ST sales office.

The value of the capacitors need not be the exact values, you can use the closest value you have got. In both cases will be an ideal choice when you need a negative 12V. The negative output voltage datazheet obtained from the Vo 3rd Pin which is datassheet read using a Multimeter. Purchasers are solely responsible for the choice, selection and use of the ST products and services described herein, and ST assumes no liability whatsoever.


The ST connector has beenhas been given to every ST performance parameter, increasing product repeatability and exceeding industry standards. 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.

All ST products are sold pursuant to ST ‘s terms and conditions of sale. No file text available.

All ST products are sold. The circuit diagram for those can be found at the datasheet given at the datssheet of this page. Previous 1 2 The Dtaasheet logo is a registered. The Input and output capacitors C1 10uF and C2 1uF are used to filter noise from the input and the output voltage respectively. Information in this document is provided solely in connection with ST products.

There are many other ways in which the IC can be used based on your application.

No abstract text available Text: Software updates You can download software updates and all the latest documentation from the ST Internetprovided solely in connection with ST products.


The output current of this IC is upto 1A, however with appropriate heat sink the datasheet says that a peak current of 2. Hence, I have interchanged the polarity of the battery.

Submitted by webmaster on 23 November LM Applications Constant V output regulator to use as power or reference voltage for analog and digital circuits. When you are designing an analog circuitthe circuit might need negative voltage either as a power source or as a reference voltage. A very basic Voltage regulator circuit is shown below.

TL — Programmable Reference Voltage. You can also check on 78 series for positive voltage regulators. STMicroelectronics NV and its subsidiaries ” ST ” reserve the right to make changes, corrections, modifications or improvements, to this document.
