LP2985AIM5-1.8/NOPB

The LP2985LV-N is a 150-mA, fixed-output voltage regulator designed to provide high performance and low noise in applications requiring output voltages ≤2 V. Using an optimized vertically integrated PNP (VIP) process, the LP2985LV-N delivers unequaled performance in all specifications critical to batterypowered designs: Ground Pin Current: Typically 825 μA at 150-mA load, and 75 μA at 1-mA load. Enhanced Stability: The LP2985LV-N is stable with output capacitor equivalent series resistance (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. 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).
