DescriptionThe LP2982 is a 50 mA, fixed-output voltage regulator designed to provide ultra low dropout and lower noise in battery powered applications.
Using an optimized VIP (Vertically Integrated PNP) process, the LP2982 delivers unequaled performance in all specifications critical to battery-powered designs:
Dropout Voltage: Typically 120 mV @ 50 mA load, and 7mV @ 1 mA load.
Ground Pin Current: Typically 375 A @ 50 mA load, and 80 A @ 1 mA load.
Sleep Mode: Less than 1 A quiescent current when on/off pin is pulled low.
Precision Output: 1.0% tolerance output voltages available (A grade).
Low Noise: By adding an external bypass capacitor, output noise can be reduced to 30 V (typical).
Four output voltage versions, from 3.0V to 5.0V, are available as standard products.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.For more information on Reliability Metrics, please click here.
