Jobs & Careers
A linear regulator for an input voltage up to 80V is offered for design  of an analog high voltage ASIC.
This regulator is able to supply the components inside the ASIC as well as external parts like microcontrollers with a stablized low voltage. An input voltage up to 80V peak or continuous can be connected to the regulator. 

Applications can be found in the industrial range or for consumer electronics where often simplest mains adapters are used.The input voltage can vary from 7V up to 80V with an output voltage of 5V.

   Data Sheet


Only small filter capacitors are necessary due to the fast response times.
An internal bandgap reference ensures an accuracy of the output voltage of less than 1%. With a quiescent current of 50ľA, this regulator can also be used as an analog ASIC for ultra-low power electronics. A current limitation and a thermal overload protection control can be integrated for circuit protection.

Where the efficiency does not demand a step-down converter, a linear regulator offers an alternative without external coil and prevents switching noise on the power lines.
