LT1175 Datasheet PDF

●The LT1175CST-5#PBF is a -5V fixed output negative low-dropout (LDO) Linear 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 (LDO) voltage and high efficiency are obtained with a unique power transistor anti-saturation design. The output can be forced to reverse voltage without damage or latchup. The increase in quiescent current during a dropout condition is actively limited. The device 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.
