DESCRIPTION  
FEATURES  
The LT®3060 is a micropower, low dropout voltage (LDO)  
linear regulator that operates over a 1.6V to 45V input  
supplyrange.Thedevicesupplies100mAofoutputcurrent  
with a typical dropout voltage of 300mV. A single external  
capacitor provides programmable low noise reference  
performance and output soft-start functionality. The  
LT3060’s quiescent current is merely 40μA and provides  
fast transient response with a minimum 2.2μF output  
capacitor. In shutdown, quiescent current is less than 1μA  
and the reference soft-start capacitor is reset.

The LT3060 optimizes stability and transient response  
with low ESR, ceramic output capacitors. The regulator  
does not require the addition of ESR as is common with  
other regulators. The LT3060 typically provides 0.1% line  
regulation and 0.03% load regulation.
