FEATURE
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,
50
μ
A operating and 16
μ
A 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 /LT1129-3.3/LT1129-5 in-
clude the ability to operate with small output capacitors.
They are stable with only 3.3
μ
F on the output while most
older devices require between 10
μ
F and 100
μ
F for stabil-
ity. Also the input may be connected to ground or a reverse
voltage without reverse current flow from output to input.
This makes the LT1129/LT1129-3.3/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 16
μ
A 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.
