International Rectifier (IR) has introduced a 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 0.4-0.66 V. 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 are said to have low ripple and low noise, with 1 per cent regulation tolerance. This makes them ideal for low-voltage point-of-load digital bus applications requiring fast transient response and output voltages from 20 to 1.8 V and an output current range of 3-10 A. Advanced PC processors can demand high jumps of current very quickly. Current steps of 300 mA to 4 A in 20 ns are not uncommon. When properly biased, IR's new regulators can provide the transient response necessary to handle this current demand.

All devices in this series are adjustable from 20 to 1.8 V and have an output current range of 3-10 A. The dropout voltage range is 0.4-0.60 V at full rated current. Input voltage range is 2.7-20 V.

The new regulators are Defense Supply Center Columbus (DSCC) 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.

The new regulators are available in a wide array of through-hole and surface-mount packages for design flexibility. Data sheets for the devices are posted on the IR Web site at www.irf.com
