LT3010/LT3010-5  
50mA, 3V to 80V  
Low Dropout  
Micropower Linear Regulator  
DESCRIPTION  
FEATURES  
The LT®3010 is a high voltage, micropower low dropout  
linear regulator. The device is capable of supplying 50mA  
output current with a dropout voltage of 300mV. Designed  
foruseinbattery-poweredorhighvoltagesystems,thelow  
quiescent current (30µA operating and 1µA in shutdown)  
makes the LT3010 an ideal choice. Quiescent current is  
also well controlled in dropout.

Other features of the LT3010 include the ability to operate  
withverysmalloutputcapacitors.Theregulatorsarestable  
with only 1µF on the output while most older devices re-  
quire between 10µF and 100µF for stability. Small ceramic  
capacitors can be used without the necessary addition of  
ESR as is common with other regulators. Internal protec-  
tion circuitry includes reverse-battery protection, current  
limiting, thermal limiting and reverse current protection.
