Santa Clara, CA--April 28, 1997--National Semiconductor Corp. (Santa Clara, CA) expanded its LP2980 line of low-dropout regulators to include a high-current output device for applications requiring up to 200mA. With the introduction of the LP2986, National advanced both the operating level and the trend to size reduction in regulators designed for battery-operated equipment. The new LDO is specified for portable applications requiring up to 200mA output current and 400mA transient peak output. Dropout voltage is typically a low 180mV at 200 mA load.
The IC is available in both the SO-8 package or the 50 percent smaller MSOP package. In addition, it includes a built-in error flag that goes low when the output drops 5 percent below nominal, and a logic-compatible shutdown control enabling the regulator to be switched on and off. Standard product versions can be pin-strapped using an internal resistive divider to provide output voltages of 5V, 3.3V, or 3.0V with guaranteed accuracy of 0.5 percent in the A-grade and 1 percent in the standard grade at room temperature. The LP2986 has fixed or fully adjustable output from 1.24V to 15V with the addition of two external resistors. A power-saving sleep mode reduces quiescent current to less than 1A (max).
Both the LP2986AIMM (MSOP package) and LP2986AIM (SO-8 package) are priced at $1.23 each in quantities of 1,000.
