What is Iout when R20 and when R25k Voltages are already kno

What is I(out) when R2=0 and when R2=5k? Voltages are already known.

All capacitors = 1uF.

VRI = VREF = 1.25 V When R2 is set at its minimum of 0 , VoUT(min) = VREF( 1 + RL) + IADjR2 = 1.25V(1) = 1.25 V When R2 is set at its maximum of 5 k VoUT(max) = VREF(1 + 2 ) + 1ADJR, = 1.25V( 1 + 220 (1) + (50AN 5 k = 29.66 V + 0.25 V = 29.9 V

Solution

I_adj=50 micro A

I_out= Vref/R1+ I_dja

=1.25/(220) + 0.05 mA

= 5.68 mA +0.05 mA

=5.73 mA
