DSCC-Qualified Linear Voltage Regulators Jan 6, 2004 12:00 PM, Edited by PETech Staff International Rectifier’s (IR) new high-current, ultralow dropout (ULDO) linear voltage regulators in high density, hermetic packages are for military and aerospace applications. The regulators feature a typical dropout voltage of 0.4 V to 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 have low ripple and low noise, with 1% regulation tolerance, making them suitable for low-voltage point-of-load digital bus applications requiring fast transient response and output voltages from 20 V to 1.8 V and an output current range of 3 A to 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. 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.
