The LT ? 1175 is a negative micropower low dropout
regulator. It features 45μA quiescent current, dropping
to 10μA in shutdown. A new reference ampli?er 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
ef?ciency are obtained with a unique power transistor
anti-saturation design. Adjustable and ?xed 5V versions
are available.

APPLICATIONS
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. Un-
like 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.
