description/ordering information
The LP2985 family of fixed-output, low-dropout regulators offers exceptional, cost-effective performance for both portable and nonportable applications. Available in voltages of 2.5 V, 2.6 V, 2.7 V, 2.8 V, 2.85 V, 3 V, 3.1 V, 3.2 V, 3.3 V, and 5 V, the family has an output tolerance of 1% for the A version (1.5% for the non-A version) and is capable of delivering 150-mA continuous load current. Standard regulator features, such as overcurrent and overtemperature protection, are included. The LP2985 has a host of features that makes the regulator an ideal candidate for a variety of portable applications:
· · · · ·
Low dropout: A PNP pass element allows a typical dropout of 280 mV at 150-mA load current and 7 mV at 1-mA load. Low quiescent current: The use of a vertical PNP process allows for quiescent currents that are considerably lower than those associated with traditional lateral PNP regulators. Shutdown: A shutdown feature is available, allowing the regulator to consume only 0.01 µA when the ON/OFF pin is pulled low. Low-ESR-capacitor friendly: The regulator is stable with low-ESR capacitors, allowing the use of small, inexpensive, ceramic capacitors in cost-sensitive applications. Low noise: A BYPASS pin allows for low-noise operation, with a typical output noise of 30 µV (RMS), with the use of a 10-nF bypass capacitor.

Small packaging: For the most space-constraint needs, the regulator is available in SOT-23 package, as well as NanoStar wafer chip scale packaging, offering an even smaller size with improved thermal and electrical characteristics. NanoStar package technology is a major breakthrough in IC packaging concepts, using the die as the package. ORDERING INFORMATION
