Ultra-Low Iq Automotive System Power Supply IC Power Saving Triple-Output Linear Regulator

The NCV8614B is a multiple output linear regulator IC’s with an Automatic Switchover (ASO) input voltage selector. The ASO circuit selects between three different input voltage sources to reduce power dissipation and to maintain the output voltage level across varying battery line voltages associated with an automotive environment.
