SNVS004J –MARCH 1999–REVISED APRIL 2013

LP2987/LP2988 Micropower, 200 mA Ultra Low-Dropout Voltage Regulator with

Programmable Power-On Reset Delay; Low Noise Version Available (LP2988)

Check for Samples: LP2987, LP2988

FEATURES

DESCRIPTION

The LP2987/8 are fixed-output 200 mA precision LDO

voltage regulators with power-ON reset delay which

can be implemented using a single external capacitor.

•

Ultra Low Dropout Voltage

•

Power-ON Reset Delay Requires Only One

Component

The LP2988 is specifically designed for noise-critical

applications. A single external capacitor connected to

the Bypass pin reduces regulator output noise.

•

Bypass Pin for Reduced Output Noise

(LP2988)

•

Specified Continuous Output Current 200 mA

Specified Peak Output Current > 250 mA

SOIC-8 and VSSOP-8 Surface Mount Packages

<2 μA Quiescent Current when Shutdown

Low Ground Pin Current at All Loads

Using an optimized VIP (Vertically Integrated PNP)

process,

these

regulators

deliver

superior

performance:

Dropout Voltage: 180 mV @ 200 mA load, and 1

mV @ 1 mA load (typical).

0.5% Output Voltage Accuracy (“A” Grade)

Wide Supply Voltage Range (16V Max)

Overtemperature/overcurrent Protection

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

Ground Pin Current: 1 mA @ 200 mA load, and 200

μA @ 10 mA load (typical).

Sleep Mode: The LP2987/8 draws less than 2 μA

quiescent current when shutdown pin is held low.

Error Flag/Reset: The error flag goes low when the

output drops approximately 5% below nominal. This

pin also provides a power-ON reset signal if a

capacitor is connected to the DELAY pin.

APPLICATIONS

•

Cellular Phone

Palmtop/Laptop Computer

Camcorder, Personal Stereo, Camera

Precision Output: Standard product versions of the

LP2987 and LP2988 are available with output

voltages of 5.0V, 3.8V, 3.3V, 3.2V, 3.0V, or 2.8V, with

specified accuracy of 0.5% (“A” grade) and 1%

(standard grade) at room temperature.
