Additional Information

The LT1129 is a micropower low dropout regulator with shutdown. The devices are capable of supplying 700mA of output current with a dropout voltage of 0.4V at maximum output.

Designed for use in battery-powered systems, the low quiescent current, 50μA operating and 16μA in shutdown, make them an ideal choice. The quiescent current does not rise in dropout as it does with many other low dropout PNP regulators.

Other features of the LT1129 include the ability to operate with small output capacitors. They are stable with only 3.3μF on the output while most older devices require between 10μF 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 LT1129-5 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.
