120V Linear Regulator for Analog ASICs
| Mainz, Germany, May 14, 2004 Linear regulators for an input voltage up to 120V as part of an analog ASIC are offered by the German ASIC manufacturer PREMA Semiconductor GmbH. 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 120V 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 120V with an output voltage of 5V. 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. PREMA offers designing and manufacturing of custom specific ICs for applications in automotive, consumer and industrial electronics as well as in building automation and telecommunications. The ModuS U6 process is suitable for analog as well as for mixed-signal circuits. Sensors like high sensitive photo transistors and hall sensors for magnetic fields as well as temperature sensors can be integrated into the ASIC by using the same process. This allows a reasonably priced one-chip solution for intelligent sensors with supply voltages up to 120V.
