LM2576T ADJ Regulator Report this article as Inappropriate to us !!!Login to Reply

I am trying to build a adjustable dc voltage regulator using LM2576 ADJ(here is the datesheet of lm2576). I have rigged up the circuit as shown in figure, But I'm not able to get the required output. There is only small variation in output voltage. Can someone please help me troubleshoot? Thanks in advance

Hi...The LM317T/LM317K/LM317AT/LM317S is a 3-terminal integrated circuit which can supply a load current of up to 1.5 Amps with an output voltage of between 1.2V and 37 Volts. It accepts an input voltage of between 3 and 40 volts.
As much as 2-3 Volts are dropped by an LM317T - i.e. if the desired output voltage is 7 Volts, the input voltage may need to be as much as 10 Volts if the output voltage is to be stable. This means that an LM317 voltage regulator cannot be used to provide a 12.0 Volt output from a 12V rated supply.
