V_INTis the internally regulated supply voltage and can

range from 9V to 11V.

V_GS(th)is the gate threshold voltage of the external pass

transistor and may be obtained from its datasheet.

Initialization

Full On

Limiting

_GS(lim)is the pass transistor gate-source voltage required

to obtain the limit curent. It is dependent on the pass

transistor’s characteristics and may be obtained from the

transfer characteristics curves on the transistor datasheet.

g_fsis the transconductance of the pass transistor and may

be obtained from its datasheet.

R_FBis the internal feedback resistor and is 5kΩ nominal.
