Product Overview

The LT1175CS8#PBF is a negative micropower Low Dropout Regulator featuring 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 an unique power transistor anti-saturation design. 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 200, 400, 600 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. Special attention was given to the problem of high temperature operation with micropower operating currents, preventing output voltage rise under no-load conditions.
