New International Rectifier DSCC-Qualified Linear Voltage Regulators Deliver 0.4V-0.66V (typ.) Dropout Voltage to High Density Military & Aerospace Applications
New hermetically-sealed devices feature one percent regulation tolerance and fast transient response
EL SEGUNDO, Calif. December 2003 - International Rectifier, IRŪ, (NYSE: IRF), today introduces a new series of high current, ultra-low dropout (ULDO) linear voltage regulators in high density, hermetic packages for military and aerospace applications. The new regulators feature a typical dropout voltage of 0.4V to 0.66V. Low dropout voltage means low power consumption, a requirement for power-restricted applications such as military and commercial aircraft, ground-based vehicles, radar and electronic warfare suites.
The ULDO DC-DC post regulator devices have low ripple and low noise, with 1% regulation tolerance, making them ideal for low-voltage point-of-load digital bus applications requiring fast transient response and output voltages from +20V to +1.8V and an output current range of 3A to 10A. Advanced PC processors can demand high jumps of current very quickly. Current steps of 300mA to 4A in 20ns are not uncommon. When properly biased, IR's new regulators can provide the transient response necessary to handle this current demand.
The new regulators are DSCC (Defense Supply Center Columbus) certified, with Standard Microcircuit Drawing (SMD) models available. IR's new regulators provide circuit designers with DSCC-qualified, components built to comply with military standards per MIL-PRF-38535/MIL-STD-883 specifications. "B" level screening per monolithic MIL-PRF-38535 is available.
Bryan Rogers, Vice President of Sales and Marketing, HiRel Products, said, "International Rectifier HiRel Products have extensive heritage in both military and aerospace industries. Our new regulators deliver superior capabilities in high density applications, and are available in a wide array of through-hole and surface-mount packages for design flexibility."
