Notes for Application Circuits:

1)

To improve the stability of output voltage , a 0.1

µF capacitor between cathode and anode of APL431L

is strongly recommended.

2)

Set V

O according to the following equation:

V

O= VREF (1+R1/ R2)+ IREF R1

3)

Choose the value for R

B as follows:

• The maximum limit for R

B should be such that the cathode current( IK) is greater than the minimum

operating current (60

µA) at V

IN (MIN) .

• The minimum limit for R

B should be such that the cathode current (IK) does not exceed 100mA under

all load conditions, and the instantaneous turn-on value for I

K does not exceed 150mA . Both of the

following conditions must be met :

R

B,MIN ≥ VIN(MAX) / 150mA ( to limit instantaneous turn-on IK)

R

B,MIN ≥ VIN(MAX) - VO / IO (MIN) + 100mA

(to limit I

K under normal operating conditions)
