hello

could you recommend any articles treating about ways of programming LDO's output voltage.

i've found one article with simple MOS switching feedback resistors.

this transistor consumes power and to have 12 levels of output i need 12 switches. this makes quiescent current larger

regards
 

You can use DAC for adjustment of LDO output voltage
