LT3032

Dual 150mA

Positive/Negative Low Noise

Low Dropout Linear Regulator

DESCRIPTION

FEATURES

TheLT^®3032isadual, lownoise, positiveandnegativelow

dropout voltage linear regulator. Each regulator delivers

up to 150mA with a typical 300mV dropout voltage. Each

regulator’s quiescent current is low (30μA operating and

<3μAinshutdown)andwell-controlledindropout,making

it an excellent choice for battery-powered circuits.

Low Quiescent Current: 30μA/Channel

Wide Input Voltage Range: 2ꢀ3V to 20V

Output Current: 150mA

Low Shutdown Current: <3μA Total (Typical)

Low Dropout Voltage: 300mV/Channel

Adjustable Outputs from 1.22V to 20V

No Protection Diodes Needed

Another key feature of the LT3032 is low output noise.

Current Limit and Thermal Limit

100kHz bandwidth. The LT3032 is stable with minimum

output capacitors of 2.2μF. The regulators do not require

the addition of ESR as is common with other regulators.

Internal protection circuitry includes reverse output prot-

ection,currentlimiting,andthermallimiting.Eachregulator

is offered as an adjustable output device with an output

voltage down to the 1.22V reference voltages.

DFN Package

APPLICATIONS

Battery-Powered Instruments

The LT3032 is available in a unique low proﬁle 14-lead

4mm × 3mm × 0.75mm DFN package with exposed back-

side pads for each regulator, allowing optimum thermal

performance.
