... The CS2001 is a smart power supply ASIC utilized in automotive airbag systems. It contains a current–mode switching regulator with a 1.2 A on–chip switch and a 5.0 V, 100 mA linear regulator. The linear output capacitor must be 3 greater with an ESR in the range of 100 the ESR of the cap is less than 100 series resistor must be used ...
