9.2.4 Low Drift Current Source
The LP2951 can be used as a low drift current source as Figure 46 shows. By connected Vout to FB, Vout will
regulated at 1.235 V, and current consumption at R is IL = 1.23/R.

9.2.5 5-V Current Limiter
The LP2950 internal current limit function can be leveraged to build 5-V current limiter as Figure 47 shows. The
minimum input-output voltage ranges from 40 mV to 400 mV, depending on load current. Current limit is typically
160 mA.
