Regulator with Slow Turn On - TL317 (CB1248E)

    This source gently applies the voltage to the load, causing it to rise slowly, thus avoiding current peaks. The TL317 is equivalent to the LM317 and the circuit is suggested in the Texas Instruments component datasheet. The integrated circuit must be mounted on a heat radiator. The transistor may be the BC558. The input voltage must be at least 2 V higher than the output voltage.
