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).
