LT3023

Dual 100mA,

Low Dropout, Low Noise,

Micropower Regulator

FEATURES

DESCRIPTION

The LT^®3023 is a dual, micropower, low noise, low drop-

out regulator. With an external 0.01μF bypass capacitor,

Low Noise: 20μV

(10Hz to 100kHz)

RMS

Low Quiescent Current: 20μA/Channel

Wide Input Voltage Range: 1.8V to 20V

Output Current: 100mA/Channel

Very Low Shutdown Current: <0.1μA

Low Dropout Voltage: 300mV at 100mA

Adjustable Output from 1.22V to 20V

Stable with 1μF Output Capacitor

Stable with Aluminum, Tantalum or

Ceramic Capacitors

output noise drops to 20μV

over a 10Hz to 100kHz

RMS

bandwidth. Designedforuseinbattery-poweredsystems,

the low 20μA quiescent current per channel makes it an

ideal choice. In shutdown, quiescent current drops to less

than 0.1μA. Shutdown control is independent for each

channel,allowingforﬂexibilityinpowermanagement.The

device is capable of operating over an input voltage from

1.8V to 20V, and can supply 100mA of output current from

each channel with a dropout voltage of 300mV. Quiescent

current is well controlled in dropout.

Reverse Battery Protected

No Reverse Current

No Protection Diodes Needed

Overcurrent and Overtemperature Protected

Thermally Enhanced 10-Lead MSOP and DFN

Packages

The LT3023 regulator is stable with output capacitors as

low as 1μF. Small ceramic capacitors can be used without

the series resistance required by other regulators.

Internal protection circuitry includes reverse battery

protection, current limiting, thermal limiting and reverse

current protection. The device is available as an adjust-

able device with a 1.22V reference voltage. The LT3023

regulator is available in the thermally enhanced 10-lead

MSOP and DFN packages.
