Features, Applications
LP2982 Micropower 50 mA Ultra Low-Dropout Regulator in SOT-23 and micro SMD Packages

The a 50 mA, fixed-output voltage regulator designed to provide ultra low dropout and lower noise in battery powered applications. Using an optimized VIPTM (Vertically Integrated PNP) process, the LP2982 delivers unequaled performance in all specifications critical to battery-powered designs: Dropout Voltage: Typically 50 mA load, and 1 mA load. Ground Pin Current: Typically 50 mA load, and 1 mA load. Sleep Mode: Less than 1 A quiescent current when on/off pin is pulled low. Smallest Possible Size: SOT-23 and micro SMD packages use absolute minimum board space. Precision Output: 1.0% tolerance output voltages available (A grade). Low Noise: By adding an external bypass capacitor, output noise can be reduced 30 V (typical). Ten output voltage versions, from to 5.0V, are available as standard products.
