LP2986

SNVS137I – MARCH 1999 – REVISED SEPTEMBER 2015

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

1 Features

3 Description

The

LP2986

is

a

200-mA

high-precision

LDO

1

•

Wide Supply Voltage Range (16 V Maximum)

regulator with a wide input voltage supply. The device

•

Ultra-Low-Dropout Voltage

has two output voltage modes: a fixed-precision

•

0.5% Output Voltage Accuracy (A Grade)

output mode and an adjustable output voltage via an

external resistive divider.

•

Ensured 200-mA Output Current

•

< 1-

μA Quiescent Current when Shutdown

Using an optimized Vertically Integrated PNP (VIP)

process, the LP2986 delivers superior performance:

•

Low GROUND Pin Current at All Loads

•

Dropout Voltage: Typically 180 mV at 200-mA

•

High Peak Current Capability (400 mA Typical)

load, and 1 mV at 1-mA load.

•

Overtemperature/Overcurrent Protection

•

GROUND Pin Current: Typically 1 mA at 200-mA

•

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

load, and 200

μA at 10-mA load.

•

Sleep Mode: The LP2986 draws less than 1

μA

2 Applications

quiescent current when SHUTDOWN pin is pulled

low.

•

Cellular Phones

•

ERROR Flag: The built-in ERROR flag goes low

•

Palmtop/Laptop Computers

when the output drops approximately 5% below

•

Camcorders, Personal Stereos, Cameras

nominal.

•

Precision Output: The standard product versions

available can be pin-strapped (using the internal

resistive divider) to provide output voltages of 5 V,

3.3 V, or 3 V with ensured accuracy of 0.5% (A

grade)

and

1%

(standard

grade)

at

room

temperature.
