CS2001 1.2A Switching Regulator, Regulator with RESET and 5V, 100mA Linear Description Features The CS2001 is a smart power supply ASIC’s internal “smartswitch”. This Linear Regulator ASIC utilized in automotive airbag switchover feature minimizes the systems. It contains a current-mode power dissipation in both the linear 5V ±2% @ 100mA switching regulator with a 1.2A on- and switcher output devices and saves Switching Regulator chip switch and a 5V, 100mA linear the cost of using a larger inductor. 1.2A Peak Internal Switch regulator. The linear output capacitor The NERD (No Energy Reserve must be 3.3µF or greater with an ESR Detected) pin is a dual function output. Voltage Tripler in the range of 100m? to 1?. If the If VOUT is not in regulation, it provides ESR o
