LP2980LV Micropower SOT, 50 m A Low-Voltage Low-Dropout Regulator For Applications With Output Voltages < 2V April 2000 LP2980LV Micropower SOT, 50 m A Low-Voltage Low-Dropout Regulator For Applications With Output Voltages < 2V General Description The LP2980LV is a 50 m A, fixed-output voltage regulator designed for high performance in applications requiring output voltages below 2V. Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2980LV delivers unequalled performance in all specifications critical to battery-powered designs: Low Ground Pin Current. Typically 280 µA @ 50 m A load, and 75 µA @ 1 m A load. Sleep Mode. Less than 1 µA quiescent current when ON/ OFF pin is pulled low. Smallest Possible Size. SOT-23 package uses absolute minimum board space. Precision Output. 0.5% tolerance output voltages available (A grade). Features n n n n n n n n n n n n Guaranteed 50 m A output current Smallest possible size (SOT-23 Package) Requires few external ponents < 1 µA quiescent current when shutdown Low ground pin current at all load currents Output voltage accuracy 0.5% (A Grade) High peak current capability (150 m A typical) Wide supply voltage range (16V max) Fast dynamic response to line and load Low ZOUT 0.1Ω typical (10 Hz to 1 MHz) Overtemperature/overcurrent protection - 40˚C to +125˚C junction temperature range Applications n n n n Cellular Phone Palmtop/Laptop puter Personal Digital Assistant (PDA) Camcorder, Personal Stereo, Camera Block Diagram DS101091-1 VIP™ is a trademark of National Semiconductor Corporation. © 2000 National Semiconductor Corporation DS101091 .national.
