RTRIM(R3) is calculated as follows:
VTRIMlow=0.3V, Regulator VREF=0.8V
The current through R3 is ITRIM=(0.8-0.3)/RTRIM
(ITRIM)(R4) > 15% of VOUT
RTRIMmax should be < the calculated value
For Example:
If Vout=3.3V, R4=63.4K, 15% of Vout=0.5V
ITRIM=8uA, RTRIM=62.5K
Therefore Rtrim standard 1% value down from 62.

The SMM105 START pin must be inactive during power-up so
that the TRIM pin is high impedence. Once power is nominal,
the START pin can be active to start margin and ADOC
functions
