FEATURES  
DESCRIPTION  
The LT®3008 series are micropower, low dropout voltage  
(LDO) linear regulators. The devices supply 20mA output  
currentwithadropoutvoltageof300mV.No-loadquiescent  
current is 3μA. Ground pin current remains at less than  
5% of output current as load increases. In shutdown,

Output Tolerance: 2% Over Load, Line and  
Temperature  
quiescent current is less than 1μA.  
The LT3008 regulators optimize stability and transient  
response with low ESR ceramic capacitors, requiring a  
minimum of only 2.2μF. 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 LT3008 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 an adjustable version with an output voltage range  
of 0.6V to 44.5V. The LT3008 is available in the thermally  
enhanced 6-lead DFN and 8-lead TSOT-23 packages.
