3 Description
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).
