9.2.2 300-mA Regulator with 0.75-V Dropout
In Figure 44, by paralleling the LP2951 together with 2x2N5432 (150mA N channel JFET), we can get a higher
output current capability around 300mA.

9.2.3 Wide Input Voltage Range Current Limiter
The LP2951 can be used as a 160-mA current limiter as Figure 45. When we connect FB to ground, the pass
element if fully turned on and out voltage will be close to input voltage. Input-output voltage ranges from 40 mV
to 400 mV, depending on load current.
*Minimum input-output voltage ranges from 40 mV to 400 mV, depending on load current. Current limit is typically 160
mA.
