Internal reference voltage VCC2-SLPE as a function of resistor RVA(REG-SLPE) for line currents between 11
and 140 mA.
In the stabilized supply application:
VLN =VCC2-SLPE + ([Ip + 0.25 × 103 A] × R15) + ([Iline 1.55 × 103 A] × R9)
In the unregulated supply application (R15 = 0
):
VLN =VCC2-SLPE + ([Iline 1.55 × 103 A] × R9)
