LT3030

Dual 750mA/250mA

Low Dropout, Low Noise,

Micropower Linear Regulator

FeaTures

DescripTion

Output Current: 750mA/250mA

TheLT^®3030isadual,micropower,lownoise,lowdropout

linear regulator. The device operates with either common

or independent input supplies for each channel, over a

1.8V to 20V input voltage range. Output 1/Output 2 supply

750mA/250mArespectivelywithatypicaldropoutvoltage

of 300mV. With an external 10nF bypass capacitor, output

Low Dropout Voltage: 300mV

Low Noise: 20μV

(10Hz to 100kHz)

RMS

Low Quiescent Current: 120μA/75μA

Wide Input Voltage Range: 1.8V to 20V

Adjustable Output: 1.220V Reference Voltage

Shutdown Quiescent Current: <1μA

Stable with 10µF/3.3µF Minimum Output Capacitor

Stable with Ceramic, Tantalum or Aluminum

Electrolytic Capacitors

noise is only 20μV

over a 10Hz to 100kHz bandwidth.

RMS

Designed for use in battery-powered systems, the low

120μA/75μA quiescent current makes it an ideal choice.

In shutdown, quiescent current drops to less than 1μA.

its precision logic threshold allows for voltage lockout

functionality. The LT3030 includes a PWRGD flag for each

channel to indicate output regulation.

TheLT3030optimizesstabilityandtransientresponsewith

low ESR ceramic output capacitors, requiring a minimum

of only 10μF/3.3μF.

applicaTions

Internal circuitry provides reverse-battery protection,

reverse-current protection, current limiting with foldback

and thermal shutdown with hysteresis. The adjustable

output voltage device has a 1.220V reference voltage.

The LT3030 is offered in the thermally enhanced 20-lead

TSSOP and 28-lead, low profile (4mm × 5mm × 0.75mm)

QFN packages.
