Other Parts Discussed in Thread: TLVH431A
Hi Team
for reference regulator using shunt regulator as below,
if Vin drops below Vout, I think Vin will be passed to Vout directly without close loop controlled.
I woul like to know the Min Vin that can make Vin bypassed to Vout directly without close loop controlled.
from the below calculation, if Vin is below 4.25V, TLVH431A will bypass Vin to Vout directly without close loop controlled ?
Min Vin = Vout + Rsup x Iout = 1.8V + 245 ohm x 10mA = 4.25V
