Demonstration circuit 893A is a triple output converter using the LTC3446 1A monolithic synchronous buck regulator with dual 300mA very low drop-out linear regulators (VLDOs). The DC893A has an input voltage range of 2.9V to 5.5V, and is capable of delivering up to 400mA of load current on the buck output and up to 300mA on each VLDO output. The buck regulator output voltage of the DC893A can be set as low as 0.8V, and the dual VLDOs can be set as low as 0.4V.
