Linear regulators specified for harsh automotive environments

Micrel has announced two new AEC-Q100 qualified, high performance linear regulators.

The MAQ5281/82 devices offer a wide input operation voltage range, up to 120V dc, and supply an output current of up to 25 or 50mA. They are suitable for the harsh environments often encountered in automotive and industrial applications. "Voltage regulators for both the automotive and industrial environments must be able to withstand large input overvoltage transient occurrences," noted Brian Hedayati, marketing vp for the analogue division at Micrel. "Micrel's new MAQ5281/82 devices are automotive qualified and feature both a wide input voltage range and an ultra low quiescent current of 6µA typical, making them ideal for automotive and rugged telecom applications." The devices feature 25/50mA guaranteed output current and an adjustable output from 1.27 to 5.5V. They can withstand up to 120V dc at input and feature a high PSRR of >90dB. Other features include a high output accuracy of + 3% accuracy, thermal shutdown and current limit protection. The devices come in a thermally efficient, 8pin ePad MSOP package option.
