LT1129/LT1129-3.3/LT1129-5

Micropower Low Dropout

Regulators with Shutdown

DESCRIPTIO

EATURE

■

The LT1129/LT1129-3.3/LT1129-5 are micropower low

dropout regulators with shutdown. The devices are ca-

pable of supplying 700mA of output current with a drop-

out 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.

Thermal Limiting

Other features of the LT1129 /LT1129-3.3/LT1129-5 in-

clude 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 stabil-

ity.Alsotheinputmaybeconnectedtogroundorareverse

voltage without reverse current flow from output to input.

This makes the LT1129/LT1129-3.3/LT1129-5 ideal for

only 16µA will flow from the output pin to ground. The

devices are available in 5-lead TO-220, 5-lead DD, and

3-lead SOT-223 packages.
