SNOS510P –NOVEMBER 1999–REVISED APRIL 2013

LP2985LV-N Micropower 150 mA Low-Noise Low-Dropout Regulator in SOT-23 and

DSBGA packages for Applications with Output Voltages ≤ 2.0V

Designed for Use with Very Low ESR Output Capacitors

Check for Samples: LP2985LV-N

FEATURES

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 ≤

2.0V.

•

Ensured 150 mA Output Current

•

Smallest Possible Size (DSBGA)

Requires Minimum External Components

Stable With Low-ESR Output Capacitor

<1 µA Quiescent Current When Shut Down

Low Ground Pin Current at all Loads

Output Voltage Accuracy 1% (A Grade)

High Peak Current Capability

Using an optimized VIP (Vertically Integrated PNP)

process, the LP2985LV-N delivers unequaled

performance in all specifications critical to battery-

powered designs:

Ground Pin Current: Typically 825 µA @ 150 mA

load, and 75 µA @ 1 mA load.

Wide Supply Voltage Range (16V Max)

Low Z_OUT: 0.3Ω Typical (10 Hz to 1 MHz)

Overtemperature/Overcurrent Protection

−40°C to +125°C Junction Temperature Range

Custom Voltages Available

Enhanced Stability: The LP2985LV-N 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: DSBGA package uses

absolute minimum board space.

APPLICATIONS

•

Cellular Phone

Precision Output: 1% tolerance output voltages

available (A grade).

Palmtop/Laptop Computer

Personal Digital Assistant (PDA)

Camcorder, Personal Stereo, Camera

Low Noise: By adding a 10 nF bypass capacitor,

output noise can be reduced to 30 µV (typical).
