Precision High-Current Series Regulator
Notes for Application Circuits:
1) To improve the stability of output voltage, a 0.1
μ
F
capacitor between cathode and anode of
APL431L is strongly recommended.
2)Set V
OUT
according to the following equation:
V
OUT
= V

3)Choose the value for R
B
as follows:
A)The maximum limit for R
B
should be such that
the cathode current(l
K
) is greater than the mini
mum operating current (80
μ
A) at V
IN(MIN)
.
B)The minimum limit for RB should be such that
the cathode current (l
K
) does not exceed 100mA
under all load conditions, and the instantaneous
turnon value for lk does not exceed 150mA. Both
of the following conditions must. be met:
