Micrel Rolls Out New 120V Linear Regulators

August 02, 2011 by Jeff Shepard

Micrel Inc. rolled out the MIC5281 and MIC5282, two high performance linear regulators designed for noise-sensitive applications such as industrial, networking, telecom infrastructure equipment and bias power supplies.

"With its industry-leading quiescent current of 6µA and PSRR of greater than 90dB, both the MIC5281 and MIC5282 offer a plethora of benefits to the designers that are focused on improving efficiency and low noise in industrial and telecom systems," noted Doyle Slack, Senior Marketing Director for Analog. "Along with these core features, the linear regulators offer the benefits of withstanding transient input voltages of up to 120V and generating a clean voltage rail to maximize system performance."

These devices operate over a very wide input operating voltage range, up to 120Vdc, and supply an output current of up to 25 and 50mA respectively. Well suited for high input voltage applications such as industrial and telecom, the MIC5281 and MIC5282 offer ±3% initial accuracy, extremely high power supply rejection ratio (>90dB) and ultra-low quiescent current of 6µA. The devices are offered in both fixed output voltage (3.3/5.0V) and adjustable output voltage (1.27 to 5.5V) options. The solutions operate over the -40 to +125°C temperature range and are available in lead-free, RoHS compliant 8-Pin ePad MSOP and 8-Pin MSOP package options.

Both the MIC5281 and MIC5282 are currently available in volume quantities, with 1K pricing starting at $1.00 and $1.10 respectively.
