LP2982AIM5-3.3/NOPB

The LP2982 is a 50-mA, fixed-output voltage LDO designed to provide ultra-low dropout and lower noise in battery-powered applications. Using an optimized vertically integrated PNP (VIP) process, the LP2982 delivers unequaled performance in all specifications critical to battery-powered designs: Dropout Voltage: Typically 120 mV at 50 mA load, and 7 mV at 1 mA load. Ground Pin Current: Typically 375 μA at 50 mA load, and 80 μA at 1 mA load. Sleep Mode: Less than 1 - μA quiescent current when ON/OFF pin is pulled low. Precision Output: 1% tolerance output voltages available (A grade). Low Noise: By adding an external bypass capacitor, output noise can be reduced to 30 μV (typical).
