OUT

= V

REF

x (1+R2/R1) + I

ADJ

x R2

Since I

ADJ

is controlled to less than 100μA, the error associated with this term is negligible

in most applications.

* = C

is required if the regulator is located near power supply filter.

**= C

is needed for stability and it improves transient response.
