The LP2954 is a 5-V micropower LDO with very low quiescent
current (90 μA typical at 1-mA load) and very low dropout voltage (typically 60 mV at light loads
and 470 mV at 250-mA load current).
The quiescent current increases only slightly at dropout (120 μA typical), which prolongs
battery life.
The LP2954 with a fixed 5-V output is available in three-pin TO-220 and DDPAK/TO-263
packages. The adjustable LP2954 is provided in an 8-pin, small-outline SOIC package. The adjustable
version also provides a resistor network which can be pin strapped to set the output to any voltage
from to 1.23 V to 29 V.
Reverse battery protection is provided for the IN pin.
The tight line and load regulation (0.04% typical), as well as very low output
temperature coefficient make the LP2954 well suited for use as a low-power voltage
reference.
Output accuracy is ensured at both room temperature and over the entire operating
temperature range.
For all available packages, see the orderable addendum at the
end of the data sheet.
