... BA3960 The BA3960 is a dual circuit, variable output, series regulator. PNP output transistors allow minimum voltage differential between input and output. Each of the two circuits can be turned on or off independently by using the system logic control. When both circuits are off, the IC keeps a standby state with no supply current. ...
