LP2985AIM5-3.3/NOPB(购买请点击) is a 150 mA, fixed-output voltage regulatordesigned to provide ultra low-dropout and low noise in battery
powered applications.Using an opt(Vertically Integrated PNP) process, delivers unequalled performance in allspecifications critical to battery-powered designs:
Dropout Voltage: Typically 300 mV @ 150 mA load, and7 mV @ 1 mA loadLP2985AIM5-3.3/NOPB(购买请点击) .
Ground Pin Current: Typically 850 μA @ 150 mA load, and75 μA @ 1 mA load.
Enhanced Stability: The LP2985 is stable with output capacitorESR as low as 5 mΩ, which allows the use of ceramiccapacitors on the output.
Sleep Mode: Less than 1 μA quiescent current when ON/OFF pin is pulled low.
Smallest Possible Size: SOT-23 and micro SMD packagesuse absolute minimum board spaceLP2985AIM5-3.3/NOPB(购买请点击) .
Precision Output: 1% tolerance output voltages available(A grade).
Low Noise: By adding a 10 nF bypass capacitor, outputnoise can be reduced to 30 μV (typical).
Multiple voltage options, from 2.5V to 5.0V, are available asstandard productsLP2985AIM5-3.3/NOPB(购买请点击) .
