Demonstration circuit 886 is an ultralow input voltage and dropout voltage supply using the 300mA output current LTC3035 linear regulator, which comes in a very small 8-pin 3mm x 2mm DFN package. The DC886 has an input voltage range from 1.7V to 5.5V and jumper selectable output voltages of 2.5V/3.3V5V or a user-determined value. Due to the 0.4V reference of the LTC3035, the DC886 is capable of supplying power to very low voltage applications, such as a (relatively) high current voltage references. The DC886 comes assembled with small 1uF ceramic capacitors to demonstrate the LTC3035's ability to maintain stability with ceramic output capacitors.
