New Device Requires Only 2.2V Input for Stable Output Voltage Regulation Between 0.9V and 1.2V

Nov 6, 2001

November 6, 2001 - Consolidating its leading linear regulator technology position, National Semiconductor Corporation (NYSE: NSM) today introduced a new linear regulator capable of regulating ultra-low output voltages between 0.9V and 1.2V.  As the industry's first 150mA linear regulator that requires an ultra low supply voltage of just 2.2V, this new device is optimized to provide low level output voltages for high-end laptop, desktop PCs, and computing add-on cards.  (http://www.national.com/pf/LP/LP2983.html)

National's LP2983 is a fixed voltage regulator with output voltage of 0.9V, 1.0V and 1.2V.  This device is designed to accommodate high-end PC market as well as digital signal processor (DSP) applications in which supply voltages require 1.2V or less, a parameter where other conventional products on the market fall short. 

Key features of National's LP2983 linear regulator include:

  • Minimum peak current of 300mA
  • Ground pin current is typically 75?A at 1mA and 850?A at 150mA load current respectively
  • Controlled shutdown for designers wishing to manage power dynamically in their system with less than 2 ?A quiescent current in shutdown mode
  • Output voltage accuracy of ?1.0% at room temperature over load and line variations and less than ?3.5% over all conditions (varying load, line, and temperature)
  • Low output capacitor requirements, 2.2?F low ESR, e.g. ceramic
  • Over-temperature and over-current protection

"National Semiconductor continues to lead the linear regulator market by providing designers with the right power supply for design efficiency and fast time-to-market," said Joe Bolsenga, strategic marketing manager of Power Management Group at National Semiconductor. "With our new LP2983 linear regulator, manufacturers of computing devices can capitalize on high performance, cost effective power management solutions."

As part of National's LP2985 linear regulator family, the LP2983 is offered in the cost-effective SOT-23 package.
Pricing and Availability
National's new LP2983 linear regulator is now available in the SOT-23 packaging and priced at $0.50 each in 1,000 units.
