LP2986 Micropower, 200 mA Ultra Low-Dropout Fixed or Adjustable Voltage Regulator

January 2002

LP2986

Micropower, 200 mA Ultra Low-Dropout Fixed or

Adjustable Voltage Regulator

General Description

The LP2986 is a 200 mA precision LDO voltage regulator

which offers the designer a higher performance version of

the industry standard LP2951.

Using an optimized VIP

鈩?/div>

(Vertically Integrated PNP) pro-

cess, the LP2986 delivers superior performance:

Dropout Voltage:

Typically 180 mV

200 mA load, and 1

1 mA load.

Ground Pin Current:

Typically 1 mA

200 mA load, and

200 碌A(chǔ)

10 mA load.

Sleep Mode:

The LP2986 draws less than 1 碌A(chǔ) 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.

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 guaran-

teed accuracy of 0.5% (鈥淎鈥?grade) and 1% (standard grade)

at room temperature.

Features

Ultra low dropout voltage

Guaranteed 200 mA output current

SO-8 and mini-SO8 surface mount packages

1 碌A(chǔ) quiescent current when shutdown

Low ground pin current at all loads

0.5% output voltage accuracy (鈥淎鈥?grade)

High peak current capability (400 mA typical)

Wide supply voltage range (16V max)

Overtemperature/overcurrent protection

鈭?0藲C to +125藲C junction temperature range

Applications

Cellular Phone

Palmtop/Laptop Computer

Camcorder, Personal Stereo, Camera
