LP2985LV Micropower 150 mA Low-Noise Low-Dropout Regulator in SOT-23 and micro SMD packages for Applications with Output Voltages ≤ 2.0V LP2985LV September 9, 2010 Micropower 150 mA Low-Noise Low-Dropout Regulator in SOT-23 and micro SMD packages for Applications with Output Voltages ≤ 2.0V Designed for Use with Very Low ESR Output Capacitors General Description The LP2985LV is a 150 mA, fixed-output voltage regulator designed to providehigh performance and low noise in appli- cations requiring output voltages ≤ 2.0V. Using an optimized VIP® (Vertically Integrated PNP) process, the LP2985LV delivers unequalled performance in all specifications critical to battery-powered designs: Ground Pin Current: Typically 825 µA @ 150 mA load, and 75 µA @ 1 mA load. Enhanced Stability: The LP2985LV is stable with output capacitor ESR as low as 5 mΩ, 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: micro SMD package uses 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).
