DESCRIPTION
The AIC1953 is a dual output linear regulator in a SOP-8 package. It is optimized for low ESR ceramic capacitors operation and up to 600mA continuous current on each output.
The AIC1953 offers high precision output voltage of 2%. At 600mA load current, a 470mV dropout is performed when output voltage is equal to 3.
