  • Abstract
    This paper presents an external control technique for the current limit in LDOs. Using an external resistor, the user can change the current limit within wide domain. This is possible by using a special block which generates the current reference for the current protection block. The block consumes between 5 and 25μA, and uses the 1.25V voltage reference. This technique was implemented within an adjustable soft-start LDO, built in a 16V CMOS technology.
