Product Overview

The LT1175IQ#PBF is a negative micro-power low-dropout Regulator 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. Several new features make the LT1175 very user-friendly. The SHDN\ pin can interface directly to positive or negative logic levels. Current limit is user-selectable at 200/400/600/800mA. 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 micro-power operating currents, preventing output voltage rise under no-load conditions.
  • Low voltage linear dropout characteristics
  • Stable with wide range of output capacitors
  • Tolerates reverse output voltage
