Refer to Section 5.7 for further details on power components design.
For the adjustable version (L7983PUR), the output voltage can be programmed through an external resistor
divider, from 0.85 V up to VIN.
The design equation is:
VOUT=0.85∙ 1+RURD
(1)
For the fixed version (L7983PU33R or L7983PU50R), the output voltage programming is achieved by simply
shorting the VOUT(FB) pin to the output capacitor.
