Hi Ayne, Your circuit will have poor voltage regulation because the output voltage is not fed back to the LM317 for error correction. Also, the LM317 regulates very well. Then the very high value of C1 in your circuit isn't needed. You should look at the datasheet for the LM317. It shows that your R2 should be a max of 120 ohms and the extra-priced LM117 should be 240 ohms max, or some of them will have their output voltage rise without a load. The datasheet also shows a High Current Adjustable Regulator circuit but it uses National's expensive unusual transistors. The datasheet for the 78xx fixed voltage regulator shows a similar but simple circuit for a High Current Regulator using a booster transistor.

Adjustment and output, the LM317 can be used as a precision current regulator. Features • Output Current in Excess of 1.5 A • Output Adjustable between 1.2 V and 37 V • Internal Thermal Overload Protection • Internal Short Circuit Current Limiting Constant with Temperature • Output Transistor Safe−Area Compensation. Industry standard LM317. Basically that of the LM317 except for the pass transistor. Buku psikologi penulis complete hausan. The thermal resistance between the IC and ambient (θJA).

You could connect a booster transistor to the LM317 the same way. Then you will have high current with excellent voltage regulation. Nonton film horor indonesia online 2017.
