Automotive Battery to 5 Volt Voltage Regulator 100mA on Globalfoundries 130nm BCD The regulator circuit has been designed to provide 5V with a load current of up to 100mA from a 12V car battery.
The regulator circuit features an automatic feedback sensing option to maintain a constant regulated output voltage level. It has been designed to provide a stable output in both low-drop and high-drop operation, while also maintaining a high performance Power Supply Rejection Ratio and minimum ripple on the output in the presence of large load current spikes inherent with supply side switching loads.
Input voltage is rated at 6 – 18V for Automotive applications however as the Regulator uses 40V-transistors, higher input voltages up to 40 V are possible with a corresponding reduction in current, so as not to exceed the maximum power dissipation of 3.5 W.
