Aeroflex Plainview Adds 7.5 A Adjustable Voltage Regulators to its HiRel Product Family

Plainview, NY - Aeroflex Plainview announces the latest addition to their HiRel Voltage Regulator Family with a new Low Dropout (LDO) 7.5Amp adjustable positive regulator. The VRG8691/92 has an adjustable 1.0V-3.3V output, which uniquely addresses trends in the satellite market requiring lower power supply voltages with higher load currents. The 7.5A VRG8691/92 is a compact-light-weight device ideally suited for supplying power to today's leading FPGA, microprocessor, ASIC, and memory chipsets for space applications.

The VRG8691/92 key features include:

o Very low dropout voltage of < 0.5V

o Tightly regulated 1.0V-3.3V output voltage (set with two external resistors)

o Internal current limit protection

o Controllable power-up sequence with Enable input and Slow-Start capability

o 100 krads(Si) total dose and -55oC to +125oC operating temperature range

o "Thru-hole" and surface mount package styles

o Available to MIL-PRF-38534, Class K

Aeroflex's comprehensive voltage regulator VRG86xx line offers the maximum design flexibility with 18 versions covering either positive or negative adjustable voltages in compact single and dual configurations. A detailed product listing with specifications and radiation performance data is available on A convenient downloadable VRG eCatalog version is also available.

"Reliable power regulation is paramount for space applications. Our voltage regulators fully address HiRel environments with space qualified DSCC SMD documented parts." said Ian Kolker, Business Development Manager, Standard Products. "The 7.5A LDO regulators are a natural extension to the HiRel Voltage Regulator line supporting higher performance and higher system on chip density technologies requiring lower power and operating voltages."

The VRG8691/92 are class K products available to DSCC SMD 5962-09237. The VRG8691/92 is $4,195, QML Class K, in lots of 100. Both Flight and Non-Flight units are readily available.
