Low Dropout Linear Regulator  
FEATURES  
DESCRIPTION  
The LT®3008 is a micropower, low dropout voltage (LDO)  
linear regulator. The device supplies 20mA output current  
with a dropout voltage of 300mV. No-load quiescent cur-  
rent is 3μA. Ground pin current remains at less than 5% of  
output current as load increases. In shutdown, quiescent  
current is less than 1μA.

Temperature  
The LT3008 regulator optimizes stability and transient  
response with low ESR ceramic capacitors, requiring a  
minimum of only 2.2μF. The LT3008 does 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.

consumption. The device is available as an adjustable  
device with an output voltage range down to the 600mV  
reference. The LT3008 is available in the 6-lead DFN and  
8-lead TSOT-23 packages.
