1 / 18 page  LP2980 Micropower 50 mA Ultra Low-Dropout Regulator General Description The LP2980 is a 50 mA, fixed-output voltage regulator de- signed specifically to meet the requirements of battery-powered applications. Using an optimized VIP™ (Vertically Integrated PNP) pro- cess, the LP2980 delivers unequaled performance in all specifications critical to battery-powered designs: Dropout Voltage. Typically 120 mV @ 50 mA load, and 7 mV @ 1 mA load. Ground Pin Current. Typically 375 µA @ 50 mA load, and 80 µA @ 1 mA load. Sleep Mode. Less than 1 µA quiescent current when ON/ OFF pin is pulled low. Smallest Possible Size. SOT-23 and micro SMD packages use an absolute minimum board space. Minimum Part Count. Requires only 1 µF of external ca- pacitance on the regulator output. Precision Output. 0.5% tolerance output voltages available (A grade). 5.0V, 3.3V, and 3.0V versions available as standard prod- ucts. Features n Ultra low dropout voltage n Output voltage accuracy 0.5% (A Grade) n Guaranteed 50 mA output current n Smallest possible size (SOT-23, micro SMD package) n Requires only 1 µF external capacitance n < 1 µA quiescent current when shutdown n Low ground pin current at all load currents n High peak current capability (150 mA typical) n Wide supply voltage range (16V max) n Fast dynamic response to line and load n Low Z OUT over wide frequency range n Overtemperature/overcurrent protection n −40˚C to +125˚C junction temperature range Applications n Cellular Phone n Palmtop/Laptop Computer n Personal Digital Assistant (PDA) n Camcorder, Personal Stereo, Camera Block Diagram Connection Diagram and Ordering Information VIP™ is a trademark of National Semiconductor Corporation.
