FEATURES  
DESCRIPTIO  
The LT®1175 is a negative micropower low dropout regu-  
lator. It features 45µA quiescent current, dropping to  
10µA in shutdown. A new reference amplifier topology  
gives precision DC characteristics along with the ability to  
maintain good loop stability with an extremely wide range  
of output capacitors. Very low dropout voltage and high  
efficiencyareobtainedwithauniquepowertransistoranti-  
saturation design. Adjustable and fixed 5V versions are  
available.

Operating Current: 45µA  
Shutdown Current: 10µA

Several new features make the LT1175 very user-friendly.  
The SHDN pin can interface directly to either positive or  
negative logic levels. Current limit is user-selectable at  
200mA, 400mA, 600mA and 800mA. The output can be  
forced to reverse voltage without damage or latchup.  
Unlike some earlier designs, the increase in quiescent  
current during a dropout condition is actively limited.

The LT1175 has complete blowout protection with current  
limiting, power limiting and thermal shutdown. Special  
attention was given to the problem of high temperature  
operation with micropower operating currents,preventing  
output voltage rise under no-load conditions. The LT1175  
is available in 8-pin PDIP and SO packages, 3-lead SOT-  
223 as well as 5-pin surface mount DD and through-hole  
TO-220 packages. The 8-pin SO package is specially  
constructed for low thermal resistance.
