The value of resistor were chosen to reduce failure r a t e c a u s e d b y
possible defective regulators, i.e., 33R are used instead of 47R or
51R for more start up current. (3.465V - 1.8V) / 33R = 50.5mA
805 package resistor are required for sufficient p o w e r ratin g
(0.1W rating). (3.465V - 1.8V) * 50.5mA = 0.085W; therefore,
smaller resistor value would require 1206 package
