LT3027

Dual 100mA,

Low Dropout, Low Noise,

Micropower Regulator with

Independent Inputs

FEATURES

DESCRIPTIO

The LT^®3027 is a dual, micropower, low noise, low drop-

out regulator with independent inputs. With an external

0.01µF bypass capacitor, output noise is a low 20µV_RMS

over a 10Hz to 100kHz bandwidth. Designed for use in

battery-poweredsystems, thelow25µAquiescentcurrent

per channel makes it an ideal choice. In shutdown, quies-

cent current drops to less than 0.1µA. Shutdown control

is independent for each channel, allowing for flexibility in

power management. 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 drop-

out voltage of 300mV. Quiescent current is well controlled

in dropout.

Ceramic Capacitors

■

Reverse Battery Protected

No Protection Diodes Needed

Overcurrent and Overtemperature Protected

Tracking/Sequencing Capability

Packages

The LT3027 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 pro-

tection, current limiting and thermal limiting protection.

The device is available as an adjustable device with a

1.22Vreferencevoltage. TheLT3027regulatorisavailable

in the thermally enhanced 10-lead MSOP and low profile

(0.75mm) 3mm × 3mm DFN packages.
