Description

General part information

LP2954 Series

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.
