Notes for Typical Application Circuits:

1. For the series regulator applications, add a compensation capacitor C1 between

CATHODE and REF is strongly recommended to improve the stability of output

voltage.

2. Set Vo according to the following equation: Vo=VREF(1+R1/R2)+IREFxR1.

3. Choose the Value for RBB as below:

(1). The maximum limit for RBB should be such that the cathode current (IK) is greater

than the minimum operating current (80uA) at VIN(MIN).

(2). The minimum limit for RBB should be such that the cathode current (IK) does not

exceed 100mA under all load conditions, and the instantaneous turn-on value for

IK does not exceed 120mA.
