LT1175IT

低压差稳压器 LT1175 - 500mA Negative Low Dropout Micropower Regulator

Description

The  LT®1175  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.
