Description
General part information
LT1175 Series
The LT1175 is a negative micropower low dropout regulator. 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 efficiency are obtained with a unique power transistor anti-saturation design. Adjustable and fixed 5V versions are available.Several new features make the LT1175 very user-friendly. TheSHDNpin 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 latch-up. 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.ApplicationsAnalog SystemsModemsInstrumentationA/D and D/A ConvertersInterface DriversBattery-Powered Systems
