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: 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

Current Limit and Thermal Limit

Another key feature of the LT3032 is low output noise.

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.

The regulators are offered as adjustable output devices

with an output voltage down to the 1.22V reference volt-

age or in ﬁxed voltages of 5V, 12V and 15V. Internal

protection circuitry includes reverse-output protection,

current limiting and thermal limiting.

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.
