Tracking Regulator  
Regulator With Trimmable Output Voltage  
906432  
Trim Procedure:  
—If VOUT is 23.08V or higher, cut out R3 (if lower, don't cut it out).  
—Then if VOUT is 22.47V or higher, cut out R4 (if lower, don't).  
—Then if VOUT is 22.16V or higher, cut out R5 (if lower, don't).  
This will trim the output to well within ±1% of 22.00 VDC, without any of the  
expense or uncertainty of a trim pot (see LB-46). Of course, this technique  
can be used at any output voltage level.
