Product Details

Demonstration circuit 811 is a dual 100mA output and dual (independent) input regulator, based on the LT3027, which consists of two identical LDO linear regulators in the 3 × 3 DFN-10 package. Each input has an input voltage range of 2.3V to 20V and a jumper-selectable output voltage of 2.5V, 3.3V, 5V or a user-defined value. The DC quiescent current, per channel, is typically only 20 uA at no load, and less than 0.1 uA in shutdown. The DC811 comes assembled with small ceramic capacitors, showing the LT3027 ability to maintain stability with ceramic output capacitors.
