The LP2985 is a 150 mA, fixed-output voltage regulator designed to provide ultra low-dropout and low noise in battery powered applications.
Using an optimized VIP? (Vertically Integrated PNP) process, the LP2985 delivers unequalled performance in all specifications critical to battery-powered designs:
Dropout Voltage: Typically 300 mV @ 150 mA load, and 7 mV @ 1 mA load.
Ground Pin Current: Typically 850 μA @ 150 mA load, and 75 μA @ 1 mA load.
Enhanced Stability: The LP2985 is stable with output capacitor ESR as low as 5 m, which allows the use of ceramic capacitors 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 packages use absolute minimum board space.
Precision Output: 1% tolerance output voltages available (A grade).
Low Noise: By adding a 10 nF bypass capacitor, output noise can be reduced to 30 μV (typical).
Multiple voltage options, from 2.5V to 5.0V, are available as standard products. Consult factory for custom voltages.
