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

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.
