The current limit is well controlled, and the chip designers had in mind that you might use it as a current limiter, as shown by the attached diagram from the LP2950 data sheet. NEC Requirements for Short Circuit Current Ratings IAEI ... Overcurrent protective device interrupting rating (IR) and equipment short circuit current rating (SCCR) are key considerations for the safety of commercial and industrial electrical systems. If inadequate overcurrent protective device IR or equipment SCCR is present, a serious potential safety hazard exists.

A possible inrush current limiting circuit could be the one in the attached image. How to Make a LED Flashlight Circuit | Homemade Circuit ... The LED flashlight circuit explained here is very simple, and it simply requires to follow the instructions as given for making it successfully. The proposed circuit utilizes just a single high bright white LED, three 1.5 volt button cells and a switch. White LED Forward Drop Voltage Current in series and parallel LED. In any series circuit exactly the same current runs through every component so the resistor and each LED will all see roughly 20mA. The LEDs control their voltage themselves as those links say so that will be around 3V each leaving about 3V across the resistor (which is presumably why you chose 150 Ohms to give you 20mA). AC Current Limiter | AVR Freaks While the resistors do set an ultimate current limit, the supplied voltage will rapidly decline or oscillate as the load draws varying currents. It could be "ok" depending on what exactly the load is. A good current limiter looks like a zero impedance driver (a voltage source) until the limit is hit, then jumps into action.
