Product Overview

The LT1129CQ#PBF is a micro-power low-dropout Regulator with shutdown. The device is capable of supplying 700mA of output current with a dropout voltage of 400mV at maximum output. Designed for use in battery-powered systems, the low quiescent current, 50µA operating and 16µA in shutdown, makes it an ideal choice. The quiescent current does not rise in dropout as it does with other low-dropout PNP regulator. Other features of the LT1129 include the ability to operate with small output capacitors. It is stable with only 3.3µF on the output while older device require between 10 and 100µF for stability. Also the input may be connected to ground or a reverse voltage without reverse current flow from output to input. This makes the LT1129 ideal for backup power situations where the output is held high and the input is at ground or reversed. Under these conditions, only 16µA will flow from the output pin to ground.
  • No protection diodes needed
  • Controlled quiescent current in dropout
  • Reverse battery protection
  • Thermal limiting
  • 50µA Quiescent current
  • Stable with 3.3µF output capacitor
