... LT3013 an ideal choice. Quiescent current is also well controlled in dropout. Other features of the LT3013 include a PWRGD fl indicate output regulation. The delay between regulated output level and fl ag indication is programmable with a single capacitor. The LT3013 also has the ability to operate with very small output capacitors. The regulator is stable with only 3.3μ ...
