8.2.9 Adjustable Regulator With Current Limiter
This application regulates to an output voltage set by the ratio of R2 and R1 and limits the output current using R3 as shown in Figure 25.
Short circuit current is approximately 600 mV/R3, or 60 mA (compared to LM317L-NZ's 200-mA current limit).
At 25-mA output only 3/4 V of drop occurs in R3 and R4.

At 25-mA output only 3/4 V of drop occurs in R3 and R4.
