SNVS137H –MARCH 1999–REVISED APRIL 2013

Micropower, 200 mA Ultra Low-Dropout Fixed or Adjustable Voltage Regulator

Check for Samples: LP2986

FEATURES

DESCRIPTION

The LP2986 is a 200 mA precision LDO voltage

•

Ultra Low Dropout Voltage

regulator which offers the designer

higher

•

Ensured 200 mA Output Current

performance version of the industry standard LP2951.

SOIC-8 and VSSOP-8 Surface Mount Packages

<1 μA Quiescent Current when Shutdown

Low Ground Pin Current at All Loads

0.5% Output Voltage Accuracy (“A” Grade)

High Peak Current Capability (400 mA Typical)

Wide Supply Voltage Range (16V Max)

Overtemperature/Overcurrent Protection

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

Using an optimized VIP™ (Vertically Integrated PNP)

process, the LP2986 delivers superior performance:

Dropout Voltage: Typically 180 mV @ 200 mA load,

and 1 mV @ 1 mA load.

Ground Pin Current: Typically 1 mA @ 200 mA

load, and 200 μA @ 10 mA load.

Sleep Mode: The LP2986 draws less than 1 μA

quiescent current when shutdown pin is pulled low.

Error Flag: The built-in error flag goes low when the

output drops approximately 5% below nominal.

APPLICATIONS

•

Cellular Phone

Precision Output: The standard product versions

available can be pin-strapped (using the internal

resistive divider) to provide output voltages of 5.0V,

3.3V, or 3.0V with ensured accuracy of 0.5% (“A”

grade) and 1% (standard grade) at room temperature.

Palmtop/Laptop Computer

Camcorder, Personal Stereo, Camera
