LT3009 Series

3µA I

, 20mA

Low Dropout Linear Regulators

FEATURES

DESCRIPTION

The LT

3009 Series are micropower, low dropout voltage

(LDO) linear regulators. The devices supply 20mA output

current with a dropout voltage of 280mV. No-load quiescent

current is 3μA. Ground pin current remains at less than

5% of output current as load increases. In shutdown,

quiescent current is less than 1μA.

The LT3009 regulators optimize stability and transient

response with low ESR ceramic capacitors, requiring a

minimum of only 1μF. The regulators do not require the

addition of ESR as is common with other regulators.

Internal protection circuitry includes current limiting,

thermal limiting, reverse-battery protection and reverse-

current protection.

The LT3009 Series are ideal for applications that require

moderate output drive capability coupled with ultralow

standby power consumption. The device is available in

ﬁxed output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V,

and as an adjustable device with an output voltage range

down to the 600mV reference. The LT3009 is available in

the 6-lead DFN and 8-lead SC70 packages.

Technology Corporation. All other trademarks are the property of their respective owners.
