Santa Clara, CA — April 19, 2004 — National Semiconductor Corporation introduces an ultra-low quiescent current low voltage dropout (LDO) regulator that expands National's portfolio of power management devices for the automotive and industrial markets.
“As the electronic content of cars steadily increases, auto makers rely more and more on high performance regulators such as National's LM9076,” said Tom Freeze, vice president of National Semiconductor's Enhanced Solutions product group. “Power systems that continue to run even after the engine is shut off – such as security, keyless entry, lighting and other 'keep alive' electronics – must draw as little current as possible and not drain the vehicle's battery. The ultra-low current of the LM9076 is ideal for these system applications.”
The LM9076, a 150mA LDO voltage regulator, is available in 5V with other voltage options to follow. It contains a variety of protection features such as thermal shutdown, input transient protection and a wide operating temperature. The LM9076 has a quiescent current of 25 microamps typical for a 0.1mA load. The LM9076 features a simplified circuit design, which is rugged enough to withstand harsh automotive environments with voltage transients up to +70V/-50V.
With a wide operating temperature range, the LM9076 is well suited for all automotive environments, from cockpit to “under the hood” applications. It features on/off control, delayed reset output and a variety of other protection features. Its current load range allows it to function in both “keep alive” and normal operations, all in a single device. Additionally, due to its wide voltage range and wide current load, this single device can be used in multiple applications.
National's LM9076 is available now in 8-pin SOIC NARROW packaging and is priced at $0.89 in 1,000-unit quantities. The LM9076 is available now in 5-pin TO 263 packaging and is priced at $0.95 in 1,000-unit quantities.
