LT3032 Series

Dual 150mA

Positive/Negative Low Noise

Low Dropout Linear Regulator

FEATURES

DESCRIPTION

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

Fixed Output Voltages: ±3.3V, ±5V, ±12V, ±15V

Adjustable Outputs from ±1.22V to ±20V

No Protection Diodes Needed

Stable with 2.2µF Output Capacitors

Stable with Ceramic, Tantalum or Aluminum Capacitors

output capacitors of 2.2µF. The regulators do not require

the addition of ESR as is common with other regulators.

Low Profile 14-Lead 4mm × 3mm × 0.75mm

DFN Package

APPLICATIONS

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.
